Solve for x using parallel line properties

x = 20/3

Step-by-step explanation:

Add 60 to both sides of the equation

12x - 60 + 60 = 3x + 60

Simplify

Add the numbers

12x = 3x + 60

Subtract 3x from both sides of the equation

12x - 3x = 3x + 60 - 3x

Simplify

combine like terms and again

9, = 60

Divide both sides of the equation by the same term

9x/9 = 60/9

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

x = 20/3
