x/6 +2=15 a. Subtract 2 from both sides of the equation.
x/6 = 13 b. Multiply both sides of the equation by 6.
x = 78 c.
x/6 +2=15 a. __________
x/6 =13 b. __________
x = 78 c. ___________
x/6 = 13 b. Multiply both sides of the equation by 6.
x = 78 c.
x/6 + 2 = 15
Proof:
Step 1: Subtract 2 from both sides of the equation.
x/6 + 2 - 2 = 15 - 2
Step 2: Simplify both sides of the equation.
x/6 = 13
Step 3: Multiply both sides of the equation by 6 to isolate x.
6 * (x/6) = 13 * 6
Step 4: Simplify both sides of the equation.
x = 78
Proving x = 78.
Given: x/6 + 2 = 15
Step 1: Subtract 2 from both sides of the equation to isolate x/6.
x/6 + 2 - 2 = 15 - 2 --> x/6 = 13 (Subtraction Property of Equality)
Step 2: Multiply both sides of the equation by 6 to solve for x.
(6)(x/6) = 6(13) --> x = 78 (Multiplication Property of Equality)
Therefore, we have proven that x = 78.
The completed two-column proof is as follows:
a. x/6 + 2 = 15 Given
b. x/6 = 13 Subtraction Property of Equality
c. x = 78 Multiplication Property of Equality
