Answer 2

-3

Explanation:

Simplifying

2x + 6 + -10x = 30

Reorder the terms:

6 + 2x + -10x = 30

Combine like terms: 2x + -10x = -8x

6 + -8x = 30

Solving

6 + -8x = 30

Solving for variable 'x'.

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

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

6 + -6 + -8x = 30 + -6

Combine like terms: 6 + -6 = 0

0 + -8x = 30 + -6

-8x = 30 + -6

Combine like terms: 30 + -6 = 24

-8x = 24

Divide each side by '-8'.

x = -3

Simplifying

x = -3
