Answer:
x = 7
Step-by-step explanation:
We are given that A, B and C are collinear points and B is in between A and C.
The length from A to B is [tex] 5[/tex], length from B to C is [tex] 3x + 7 [/tex] and AC is [tex] 5 x - 2 [/tex].
We are to find the value of x.
[tex] A B + B C = A C [/tex]
[tex] 5 + 3 x + 7 = 5 x - 2 [/tex]
[tex] 5 x - 3 x = 5 + 7 + 2 [/tex]
[tex] 2 x = 1 4 [/tex]
[tex] x = \frac { 1 4 } { 2 } [/tex]
x = 7
