Answer 2

Answer:

$\Huge\boxed{X=7}$

Step-by-step explanation:

Isolate x on one side of the equation.

3x+7=35-x

3x+7-7=35-x-7 (First, subtract 7 from both sides.)

35-7 (Solve.)

35-7=28

3x=-x+28

3x+x=-x+28+x (Add x from both sides.)

3x+x (Solve.)

3x+x=4x

4x=28

4x/4=28/4 (Then, divide by 4 from both sides.)

28/4 (Solve.)

28/4=7

x=7

$\Rightarrow \Large\boxed{X=7}$

So, the correct answer is x=7.
