Question

How many solutions does the following equation have?3(x+5)=−4x+8

Answer 1

1 solution, x = -1.

Explanation:

3(x + 5 )= −4x + 8

3x + 15 = -4x + 8

3x + 4x = 8 - 15

7x = -7

x = -1.

Answer 2

1

Explanation:

Solve the equation for x:

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

Distribute.

3x + 15 = -4x + 8

Combine like terms.

3x + 15 = -4x + 8

+4x +4x

7x + 15 = 8

-15 -15

7x = -7

Divide both sides by 7.

x = -1

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