What is the answer of this equation? 10x-6 (2x+5) = 20

Simplifying

x = - 25

Step-by-step explanation:

Reorder the terms:

10x + - 6 (5 + 2x) = 20

10x + (5 * - 6 + 2x * - 6) = 20

10x + (-30 + - 12x) = 20

Reorder the terms:

-30 + 10x + - 12x = 20

Combine like terms: 10x + - 12x = - 2x

-30 + - 2x = 20

Solving

-30 + - 2x = 20

Solving for variable 'x'.

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

Add '30' to each side of the equation.

-30 + 30 + - 2x = 20 + 30

Combine like terms: - 30 + 30 = 0

0 + - 2x = 20 + 30

-2x = 20 + 30

Combine like terms: 20 + 30 = 50

-2x = 50

Divide each side by '-2'.

x = - 25
