Answer:
Step-by-step explanation:
If M s the mid point of the line XY, then XM+MY = XY and XM= MY
Given
XM = 2x+7
MY = 8x-23
Since XM = XY, then;
2x+7 = 8x - 23
2x-8x = -23-7
-6x = -30
x = -30/-6
x = 5
Get XM
XM = 2x+7
XM = 2(5)+7
XM = 10+7
XM = 17
Get MY:
MY = 8x-23
MY = 8(5)-23
MY = 40-23
MY = 17
Since XY = XM+MY
XY = 17+17
XY = 34
