Question

2 ^ 5 x 3 - 3(x + 1) = 42 

nhanh hộ mình ạ

 

 

Answer 1

2⁵ x 3 - 3( x + 1 ) = 42

⇒ 96 - 3( x + 1 ) = 42

⇒ 3( x + 1 ) = 54

⇒ x + 1 = 18

⇔ x = 17.

Vậy x = 17.

Answer 2

\(2^5\times3-3\times\left(x+1\right)=42\)

\(32\times3-3\times\left(x+1\right)=42\)

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

\(3\times\left(x+1\right)=54\)

\(x+1=18\)

\(x=17\)
