Question

Complete the two-column proof.

Answer 1

Answer:

This is proved with two property of equality subtraction and multipication property.

Step-by-step explanation:

Given $\frac{x}{6} + 2 = 15$

By subtraction property of equality

           $\frac{x}{6} +2 - 2 = 15 - 2$

      ⇒  $\frac{x}{6} = 13$

Now by multiplication property

          x = 13(6) = 78

Hence the result.

Answer 2

$\frac{x}{6} + 2 = 15$ ⇒ Start with equality property

$\frac{x}{6}=13$ ⇒ Using the subtraction/addition property  to subtract 2 from both sides

$x = 78$ ⇒ Using the multiplication property (multiply both sides by 6)

x = 78
