Answer:

3

Step-by-step explanation:

Let's start by simplifying the parenthesis. Distribute the 3 to the terms in it.

3x + 2 + 3 + 3x = 23

Simplify the like terms.

6x + 5 = 23

Isolate the x term by subtracting 5 on both sides.

6x = 18

Divide both sides by 6 to get the value of x.

x = 3

distribute the 3(1+x) to get 3+3x
the equation is now 3x+2+3x+3=23
next add like terms to get 6x+4=23
next subtract the 5 on both sides to get 6x= 18
then divide by 6 on both sides to get 3.
so the answer is 3
