Question

Ac=22 bc=x+14 ab=x+10 find x

Answer 1

AB + BC = AC                 Segment Addition Postulate

(x + 10) + (x + 14) = 22     Substitution

2x + 24 = 22                   Simplify (added like terms)

2x = -2                            Subtraction Property of Equality

x = -1                               Divison Property of Equality

Answer: x = -1
