Answer:x=-10.88

Explanation:

Simplifying

72.48 + 6x = 18.08 + x

Solving

72.48 + 6x = 18.08 + x

Solving for variable 'x'.

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

Add '-1x' to each side of the equation.

72.48 + 6x + -1x = 18.08 + x + -1x

Combine like terms: 6x + -1x = 5x

72.48 + 5x = 18.08 + x + -1x

Combine like terms: x + -1x = 0

72.48 + 5x = 18.08 + 0

72.48 + 5x = 18.08

Add '-72.48' to each side of the equation.

72.48 + -72.48 + 5x = 18.08 + -72.48

Combine like terms: 72.48 + -72.48 = 0.00

0.00 + 5x = 18.08 + -72.48

5x = 18.08 + -72.48

Combine like terms: 18.08 + -72.48 = -54.4

5x = -54.4

Divide each side by '5'.

x = -10.88

Simplifying

x = -10.88
