To solve for x in the first equation, we will first isolate x by adding 59 to both sides:

32x - 59 + 59 = 453 + 59
32x = 512

Next, we divide by 32 to solve for x:
x = 16

For the second equation, we first add 23 and 312 together to find y:
y = 23 + 312
y = 335

Lastly, to solve for x in the third equation, we first multiply 67 by (120 - x) and then divide 7035 by the result to find x:

7035 = 67(120 - x)
7035 = 8040 - 67x
67x = 1005
x = 15
