Question

- 7x + 5(2x - 1) = -20​

Answer 1

x = -5

Explanation:

-7x + 5(2x - 1) = -20 (Given)

-7x + 10x - 5 = -20 (Simplify)

3x - 5 = -20 (Simplify)

3x - 5 + 5 = -20 + 5 (Addition Property of Equality)

3x = -15 (Simplify)

`(3x)/(3) = (-15)/(3)` (Division Property of Equality)

x = -5 (Simplify)

Answer 2

x= -5

Explanation:

-7x + 5(2x - 1) = -20

-7x + 10x - 5 = -20

3x -5 = -20

3x = -15

x = -5
