Question

If Q is the midpoint of PR, find x when PR=2x and PQ=2x-12.

Answer 1

Answer: x=12

Step-by-step explanation:

You start with: $2x\neq 2x-12$

The segment PQ is half of PR, so to make both sides equal the PQ side must be doubled.

$2x=4x-24$

Then all x-values should be put on one side of the equation.

$2x-4x=-24$

Combine like terms.

$-2x=-24$

Then simplify.$x=12$
