5x=73

X=73/5 or 14.6

Answer 2

Answer:

x = 10

Explanation: I'm giving you an example of another problem so next time you would know how to do it.

Simplifying

5x + 4x + 90 = 180

Reorder the terms:

90 + 5x + 4x = 180

Combine like terms: 5x + 4x = 9x

90 + 9x = 180

Solving

90 + 9x = 180

Solving for variable 'x'.

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

Add '-90' to each side of the equation.

90 + -90 + 9x = 180 + -90

Combine like terms: 90 + -90 = 0

0 + 9x = 180 + -90

9x = 180 + -90

Combine like terms: 180 + -90 = 90

9x = 90

Divide each side by '9'.

x = 10

Simplifying

x = 10
