Answer :
Answer: 5 = x
Step-by-step explanation: Since b is between a and c, the segment addition postulate says that
ab + bc = ac
Substituting the expressions into that equation we get:
(x + 6) + (3x - 2) = 6x - 6
Combining like terms and then solving we get:
4x + 4 = 6x - 6
4 = 2x - 6
10 = 2x
5 = x
