Question

Suppose Q is the midpoint of PR.
PQ = 3x + 14 and QR = 32; Find x

Answer 1

X = 6

Explanation:

Because q is the midpoint the two points will equal each other

PQ = QR

3x + 14 = 32

3x = 18 (subtract 14 from both sides)

X = 6 (divide 3 from both sides)

Answer 2

x=6

Explanation:

if Q is the midpoint, then its halfway. That means PR=PQ+QR

which means PQ=QR

so...32=3x+14

subtract 14 from both sides

18=3x

divide both sides by 3

18/3=6

3x/3=x

so

x=6
