Which expression is equivalent to 4x+20?

4x+20=

6x-10

Step-by-step explanation:

Simplifying: 4x + 20 = 6x + - 10

Reorder the terms: 20 + 4x = 6x + - 10

Reorder the terms: 20 + 4x = - 10 + 6x

Solving: 20 + 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: 20 + 4x + - 6x = - 10 + 6x + - 6x

Combine like terms: 4x + - 6x = - 2x: 20 + - 2x = - 10 + 6x + - 6x

Combine like terms: 6x + - 6x = 0: 20 + - 2x = - 10 + 0: 20 + - 2x = - 10

Add '-20' to each side of the equation: 20 + - 20 + - 2x = - 10 + - 20

Combine like terms: 20 + - 20 = 0: 0 + - 2x = - 10 + - 20: - 2x = - 10 + - 20

Combine like terms: - 10 + - 20 = - 30: - 2x = - 30

Divide each side by '-2': x = 15

Simplifying: x = 15
