Yes they are both like terms so if they are in the same equation you can just add them together.

10/12 = (3x+2)/(5x-0.4)
10(5x-0.4) = 12(3x+2)
50x - 4 = 36x + 24
50x - 36x = 24 + 4
14x = 28
x = 28/14
x = 2
QS = 3x + 2 = 3*2 + 2 = 6 + 2 = 8
SR = 5x - 0.4 = 5*2 - 0.4 = 10 - 0.4 = 9.6
Answer is QS=8, SR=9.6

Let x represent the number of grandstand seats on race track #2
The number of grandstand seats on race track #1 = 37,000 + 3x
Total number of seats together = 289,000
So, we can frame the equation as follows:
37,000 + 3x + x = 289,000
4x + 37,000 = 289,000
4x = 289,000-37,000 = 252,000
4x = 252,000
x = 252,000/4
x = 63,000
Number of seats on race track #2= x = 63,000 seats
Number of seats on race track #1 = 37000+3x = 37000+3*63000 = 226,000 seats
Answer:
-1/2x+1 is the equation.
