I need help with the midpoint of line segment?
If I dont know the distance of WY but I know the equation of WX and of XY
WX= 7x+8 and XY= 5x+12 and I need to solve for x and the lines have to be equal to eachother, I can't get it right please help.

Never fear, Jaws is here!
You have to set the equations equal to each other and solve for x:
7x + 8 = 5x = 12
2x + 8 = 12 (I subtracted 5x from both sides)
2x = 4 (I subtracted 8 from both sides)
x = 2 (I divided both sides by 2)
Now plug x back into one of the equations:
7(2) + 8
14 + 8
That means that the length of WX is 22, the length of XY is 22, and the length of WY is both combined, or 44.
