7 0

Answer:

1

Step-by-step explanation:

Solve the equation for x:

3(x + 5) = -4x + 8

<em>Distribute.</em>

3x + 15 = -4x + 8

<em>Combine like terms.</em>

3x + 15 = -4x + 8

+4x         +4x

7x + 15 = 8

     -15   -15

7x = -7

<em>Divide both sides by 7.</em>

x = -1

The following equation has one solution, x = -1.

1. -5(x - 2) - (x + 2) = 50
Serjik [45]

Answer:

x = - 7

Step-by-step explanation:

Given

- 5(x - 2) - (x + 2) = 50 ← distribute parenthesis on left side

- 5x + 10 - x - 2 = 50, that is

- 6x + 8 = 50 ( subtract 8 from both sides )

- 6x = 42 ( divide both sides by - 6 )

x = - 7
