If 3x plus 2 equals 90 then what is the value of x

Firdavs [7]

Hello!

$3x+2=90$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 2 from both sides of the equation.

$3x+2-2=90-2$

Simplify

$3x=88$

Then you divide by 3 from both sides of the equation.

$\frac{3x}{3}=\frac{88}{3}$

Simplify it should be the correct answer.

$x=\frac{88}{3}$

Answer⇒⇒⇒⇒⇒x=88/3

Hope this helps!
