Answer: x=6

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*(3+x)-7-(x+5)=0

(2 • (x + 3) -  7) -  (x + 5)  = 0

x - 6  = 0

 Solve  :    x-6 = 0  

Add  6  to both sides of the equation :  

                     x = 6

Answer:

x = 6

Step-by-step explanation:

2(3+x)-7=x+5

We move all terms to the left:

2(3+x)-7-(x+5)=0

We add all the numbers together, and all the variables

2(x+3)-(x+5)-7=0

We multiply parentheses

2x-(x+5)+6-7=0

We get rid of parentheses

2x-x-5+6-7=0

We add all the numbers together, and all the variables

x-6=0

We move all terms containing x to the left, all other terms to the right

x=6
