Question

- 7x + 5(2x - 1) = -20​

Answer 1

Answer:

x= -5

Step-by-step explanation:

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

-7x + 10x - 5 = -20

3x -5 = -20

3x = -15

x = -5

Answer 2

Answer:

x = -5

Step-by-step 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)

$\frac{3x}{3} = \frac{-15}{3}$ (Division Property of Equality)

x = -5 (Simplify)
