Complete the two-column proof. given: x/6 + 2 =15 prove: x = 78 x/6 + 2 =15 a. x/6= 13 b. x = 78 c.

The equation you start with is the given equation.
x/6 + 2 = 15 a. Given

The next step in solving this equation is subtracting 2 from both sides.
x/6 = 13 b. Subtraction Property of Equality

Lastly, to cancel out the denominator, multiply both sides of the equation by 6.
x = 78 c. Multiplication Property of Equality

a. Given
b. Subtraction Property of Equality
c. Multiplication Property of Equality
