Sagot :

The equation only has one solution which is five

Answer:

This many.

Step-by-step explanation:

Simplifying

5 = 5x + -20

Reorder the terms:

5 = -20 + 5x

Solving

5 = -20 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

5 + -5x = -20 + 5x + -5x

Combine like terms: 5x + -5x = 0

5 + -5x = -20 + 0

5 + -5x = -20

Add '-5' to each side of the equation.

5 + -5 + -5x = -20 + -5

Combine like terms: 5 + -5 = 0

0 + -5x = -20 + -5

-5x = -20 + -5

Combine like terms: -20 + -5 = -25

-5x = -25

Divide each side by '-5'.

x = 5

Simplifying

x = 5
