4х+7+(х+4)=(2-х)+15

4х + 7 + (х + 4) = (2 - х) + 15

First, let's simplify the equation step by step:

4х + 7 + (х + 4) = 2 - х + 15

Combine like terms within parentheses:

4х + 7 + х + 4 = 2 - х + 15

Combine like terms on both sides:

5х + 11 = 17 - х

Move х term to the left side by adding х to both sides:

5х + х + 11 = 17

Combine like terms:

6х + 11 = 17

Move constant term to the right side by subtracting 11 from both sides:

6х = 17 - 11

Simplify:

6х = 6

Divide both sides by 6 to solve for х:

х = 1

Ответ: х = 1
