The value of x from the given expression is -8
Addition postulate
Given the following expression
AC = 8
AB = 23+2x
and BC = 2x+17
Using the addition property, we will have:
AC = AB + BC
Substitute the expression to have:
8 = 23+2x + 2x + 17
-15 = 4x + 17
4x = -32
x = -8
Hence the value of x from the given expression is -8
