68 nhé mik k bạn rồi

Tìm x bít

5(x+35)=515

   x+35 =515:5

   x+35 =103

   x       =103-35

   x       = 68

Vậy x = 68 .

\(5\left(x+35\right)=515\)

\(5x+175=515\)

              \(5x=515-175\)

               \(5x=340\)

                 \(x=68\)

5(x+35)=515

x+35=515:5

x+35=103

x=103-35=68

5 (x + 35) = 515

     x + 35  = 515 : 5

     x + 35  = 103

     x           = 103 - 35

     x           = 68

5(x+35)=515 có ai biết thì trả lời giùm mình nhé nhanh lên nha

5 (x + 35) = 515

     x + 35  = 515 : 5

     x + 35  = 103

     x           = 103 - 35

     x           = 68

541+(218-x)=375

541+218-x=375

759-x=375

x=384

5 .(x+35)=515

x+35=103

x=68

10+2.x=4^5:4

10+2.x=256

2x=246

x=123

96-3.(x+1)=42

3(x+1)=54

x+1=18

x=17

=.= hok tốt!!

\(541+\left(218-x\right)=375.\)

\(\Leftrightarrow218-x=-166\)

\(\Leftrightarrow x=218-\left(-166\right)\)

\(\Leftrightarrow x=384\)

\(5.\left(x+35\right)=515\)

\(\Leftrightarrow x+35=103\)

\(\Leftrightarrow x=103-35\)

\(\Leftrightarrow x=68\)

\(10+2x=4^5:4\)

\(\Leftrightarrow10+2x=4^4\)

\(\Leftrightarrow10+2x=256\)

\(\Leftrightarrow2x=256-10\)

\(\Leftrightarrow2x=246\)

\(\Leftrightarrow x=123\)

\(96-3.\left(x+1\right)=42\)

\(\Leftrightarrow3.\left(x+1\right)=96-42\)

\(\Leftrightarrow3\left(x+1\right)=54\)

\(\Leftrightarrow x+1=54:3\)

\(\Leftrightarrow x+1=18\)

\(\Leftrightarrow x=17\)

541 + ( 218 - x ) = 375

<=> 218 - x = 375 - 541

<=> 218 - x = -166

<=> x = 218 + 166

<=> x = 384

1) \(541+\left(218-x\right)=375\)

\(\Leftrightarrow759-x=375\)

\(\Leftrightarrow x=384\)

2) \(5\cdot\left(x+35\right)=515\)

\(\Leftrightarrow x+35=103\)

\(\Rightarrow x=68\)

3) \(96-3\cdot\left(x+1\right)=42\)

\(\Leftrightarrow3\cdot\left(x+1\right)=54\)

\(\Leftrightarrow x+1=18\)

\(\Rightarrow x=17\)

4) \(2\cdot x-138=2^3\cdot3^2\)

\(\Leftrightarrow2\cdot x-138=72\)

\(\Leftrightarrow2\cdot x=210\)

\(\Rightarrow x=105\)

[ ( 6 x - 7² ) : 2 - 84 ] . 28 = 5628

[ ( 6 x - 7² ) : 2 - 84 ] = 5628 : 28

[ ( 6 x - 7² ) : 2 - 84 ] = 201

[ ( 6 x - 49 ) : 2 - 84 ] = 201

[ ( 6 x - 49 ) - 84 ] = 201 . 2 

[ ( 6 x - 49 ) - 84 ] = 402

( 6 x - 49 ) = 402 + 84

( 6 x - 49 ) = 486

6 x  = 486 + 49 

6 x  = 535

 x = 535 : 6

x = 84

Thế để mình làm lại cho vậy, khổ ghê:

520 + 6,5 x 4 = \(\frac{X+175}{5}\)+ 30

520 + 26 = \(\frac{X+175}{5}\)+ 30

546 = \(\frac{X+175}{5}\)+ 30

\(\frac{X+175}{5}=546-30\)

\(\frac{X+175}{5}=516\)

\(\frac{X+175}{5}=\frac{2580}{5}\)

X + 175 = 2580

X = 2580 - 175

X = 2405

520 + 6,5 x 4 = X + \(\frac{175}{5}\)+ 30

520 + 26 = X + 35 + 30

546 = X + 65

X = 546 - 65

X = 481

bạn ơi x + 175 phần 5 cỏ chứ ko phải như bạn nghĩ đâu

trả lời tiếp nè

c) 3.(x+1)=96-42

3.(x+1)=54

x+1=54:3

x+1=18

x=18-1

x=17

tick nha

218 - x = 735-541

218 - x = 194

x         =  218 - 194 

x          =  24

Đúng 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

1,

a,1100+(-100)=1000

b,(2017)+2010=-7

c,/-102/+36=138

d,/-1002/+(-102)=900

e,(-1002)+(-102)+515=589

a ) 5*(x+35) =515

=>x+35=515:5

=>x+35=103

=>x=103-35

=>x=68

\(5.\left(x+35\right)=515\)

\(x+35=515:5\)

\(x=68\)

5x(x+35)=515
