56°
57°
85
2x
4x

Answers

Answer:

56

Step-by-step explanation:

Simplifying

x + 7x = 56 + 8

Combine like terms: x + 7x = 8x

8x = 56 + 8

Combine like terms: 56 + 8 = 64

8x = 64

Solving

8x = 64

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '8'.

x = 8

Simplifying

x = 8
