Question

Solve for xxx. -30=5(x+1)

Answer 1

EQUATION

Exercise: -30 = 5(x + 1)

First, apply the distributive property:

-30 = 5(x + 1)

-30 = 5x + 5

Substract 5 from both sides:

-30 - 5 = 5x + 5 - 5

-35 = 5x

Divide both sides by 5:

`\mathsf{(-35)/(5) = (5x)/(5)}`

`\large{\boxed{\mathsf{-7 = x}}}`

‎

Let's check the answer:

-30 = 5(x + 1)

-30 = 5(-7 + 1)

-30 = 5(-6)

-30 = -30

The answer is correct.

Answer. The value of x = -7.
