Rewrite in simplest terms (-4x - 10) + (6x - 10)

2x-20

Step-by-step explanation:

Simplifying

4x + -10 = 6x + 10

Reorder the terms:

-10 + 4x = 6x + 10

Reorder the terms:

-10 + 4x = 10 + 6x

Solving

-10 + 4x = 10 + 6x

Solving for variable 'x'.

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

Add '-6x' to each side of the equation.

-10 + 4x + -6x = 10 + 6x + -6x

Combine like terms: 4x + -6x = -2x

-10 + -2x = 10 + 6x + -6x

Combine like terms: 6x + -6x = 0

-10 + -2x = 10 + 0

-10 + -2x = 10

Add '10' to each side of the equation.

-10 + 10 + -2x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + -2x = 10 + 10

-2x = 10 + 10

Combine like terms: 10 + 10 = 20

-2x = 20

Divide each side by '-2'.

x = -10

Simplifying

x = -10
