Question 493069: I have a diagram that looks like an x but with a horizontal line through it. The top right (split by the horizontal line) angle is 5x+4. The bottom right is 3x-24. The very bottom is 2y. On the left the bottom split angle is 2y. Can you please help me I really don't understand what I am doing. I know that I have to solve for the variables, but I am totally an algebra person and don't really do well with diagrams. I tried making the 3x-24=114 and got 46 for my answer, then I put 46 in for x on 5x+4 and got 234. Please help! I really am lost, please and very thank you!!!!

You can put this solution on YOUR website! It sounds as if the two angles on the top right are adjacent angles that combine to form a straight line of 180 degrees, they are supplementary.
5x +4 + 3x - 24 = 180
8x -20 = 180
8x = 200
x = 25
5(25) + 4 = `129 degrees
3(25) -24 = 51 degrees
129 degrees + 51 degrees = 180 degrees.
This does check.

The second part with the y variable is not clear, if you could describe it better we could try to work out an answer.
Cleomenius.
