7x+8
9x - 4
Solve for x

hope this help:)

Step-by-step explanation:

Simplifying

(7x + 8) = (9x + -4)

Reorder the terms:

(8 + 7x) = (9x + -4)

Remove parenthesis around (8 + 7x)

8 + 7x = (9x + -4)

Reorder the terms:

8 + 7x = (-4 + 9x)

Remove parenthesis around (-4 + 9x)

8 + 7x = -4 + 9x

Solving

8 + 7x = -4 + 9x

Solving for variable 'x'.

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

Add '-9x' to each side of the equation.

8 + 7x + -9x = -4 + 9x + -9x

Combine like terms: 7x + -9x = -2x

8 + -2x = -4 + 9x + -9x

Combine like terms: 9x + -9x = 0

8 + -2x = -4 + 0

8 + -2x = -4

Add '-8' to each side of the equation.

8 + -8 + -2x = -4 + -8

Combine like terms: 8 + -8 = 0

0 + -2x = -4 + -8

-2x = -4 + -8

Combine like terms: -4 + -8 = -12

-2x = -12

Divide each side by '-2'.

x = 6

Simplifying

x = 6
