Answer:
Top: 39
Bottom: 143
Explanation:
first you need to find x after setting up your equation
which would be: -4x + 5 -13x + 39= 180
(it would equal 180 because both equations sit on straight line, let me know if you have any questions about this)
After setting up the equation you would find the like terms: -4x and -13x are one pair of like terms, 5 and 39 being the other. Combine like terms: -17x +44 =180
Now we need to get rid of the 44. Since it is positive we would need to subtract so that 44 cancels out, then we subtract 44 from 180 (what we do to one side of the equation we do to the other) and that leaves us with -17x=136.
Now we divide -17 on both sides to find out x: x= -8
finally you can just plug in -8 in for x in each problem
