a) x – 32 : 16 = 48 ó x – 2 = 48 ó x = 48 + 2 ó x = 50

b) 88 – 3.(7+x) = 64 ó 3.(7+x) = 88 – 64 ó 7 + x = 24:3 ó x = 8 – 7 ó x = 1

c) (5+4x) : 3 – 121 : 11 = 4 ó (5+4x) : 3 – 11 = 4 ó (5+4x) : 3 = 4 + 11 ó 5+4x = 15.3 ó 4x = 45 – 5 ó 4x = 40 ó x = 10

d) 15 – 2(3x+1) = 11.13 – 130 ó 15 – 2(3x+1) = 143 – 130 ó 15 – 2(3x+1) = 13

ó 2(3x+1) = 15 – 13 ó 3x + 1 = 2:2 ó 3x = 1 – 1 ó 3x = 0 ó x = 0

\(5x+3x=88\)

\(x.\left(5+3\right)=88\)

\(x.8=88\)

\(x=88:8\)

\(x=11\)

$5x+3x=88$

$\Rightarrow8x=88$

$\Rightarrow x=88:8$

$\Rightarrow x=11(tm)$

Vậy $x=11$.

`#3107.101107`

\(5x+3x=88\\ \Rightarrow x\left(5+3\right)=88\\ \Rightarrow8x=88\\ \Rightarrow x=88\div8\\ \Rightarrow x=11\)

Vậy, `x = 11.`

e có chép nhầm để ko cj hấy ra số thập phân

a,x+55=88

x=88-55

x=33

b,x =0

a,x+55=88

  x=88-55

x=33

tick nha

a) x= 33

b) x= 0 ; x= 3 hoặc -3

nhớ **** mk nha
