Simplifying

4.5x + -7 = 20

Reorder the terms:

-7 + 4.5x = 20

Solving

-7 + 4.5x = 20

Solving for variable 'x'.

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

Add '7' to each side of the equation.

-7 + 7 + 4.5x = 20 + 7

Combine like terms: -7 + 7 = 0

0 + 4.5x = 20 + 7

4.5x = 20 + 7

Combine like terms: 20 + 7 = 27

4.5x = 27

Divide each side by '4.5'.

x = 6

Simplifying

x = 6
