Ta có:
\(14x-6x=200\)
\(\Rightarrow8x=200\)
\(\Rightarrow x=25\)
Vậy: x = 25
14x - 6x = 200
( 14 - 6)x = 200
8x = 200
=> x = 200 ÷ 8
=> x = 25
Vậy x = 25
Ta có :
14x-6x = 200
\(\Leftrightarrow\)8x= 200
\(\Rightarrow\)x = 200/8
x= 25
Ta có:
\(14x-6x=200\)
\(\Rightarrow8x=200\)
\(\Rightarrow x=25\)
Vậy: x = 25
14x - 6x = 200
( 14 - 6)x = 200
8x = 200
=> x = 200 ÷ 8
=> x = 25
Vậy x = 25
Ta có :
14x-6x = 200
\(\Leftrightarrow\)8x= 200
\(\Rightarrow\)x = 200/8
x= 25
Tìm x:14x-6x=23.52
tìm x: 14x-6x=23.52
tìm x :
a/ 6x - 35 + 5x - 21 = 17x - 20
b/ 5x + 35 - 4x - 27 = 14x + 34
a,x-280:35=554
b,x+(5÷3)=500
c,390:(5x-5)=39
d,34x-14x=200
Tìm x, biết:
1) 14x - 5 = 8x + 10
2) 15 + 5x = 3x + 30
3) 2x - 5 = 15- 3x
4) 2 ( 3x + 5 ) + 3 ( x + 1 ) = 6x + 20
5) 4 ( x - 3 0 + 5 ( x - 3 ) = 18
(6x-8)3-35 x 25=200
Hãy tìm x
Bài 2. tìm số nguyên x,biết
a,87-(73-x)=20
b,575-(6x+70)=445
c,(7.x-11)mũ 3 = 2 mũ 5.5 mũ 2=200
Tìm x
A. (x+1)+(x+2)+(x+3)+...+(x+100)=10050
B. (2x-1)+(4x-2)+(6x-3)+...+(400x-200)=5+10+...+1000
tìm x:
1) 25x + 3 ( 4- 6x ) = 50
2) 4 ( 2x + 3 ) + 2 ( 3x + 1) = 120
3) 2 ( 3x + 2 ) + 3 ( 4x + 1 ) = 200
