Hello from MrBillDoesMath!
Answer: Case 1: approximately 429.4, Case 2: 8
Discussion:
Let the unknown be "x". The problem statement could mean either
32 * (435 -x) = 179 (#1)
or
435 - 32*x = 179 (#2)
It's unclear which one is wanted so we solve both of them.
----------------------------------------------#1
But for case #1
32 * (435 -x) = 179
32 * 435 - 32x = 179 or
13920 - 32x = 179
Add 32x to both sides
13920 = 179 + 32x
Subtract 179 from both sides:
13920 - 179 = 32x
Divide both side by x to get
x = (13920 -179)/32 = 13741/32 which is approximately 429.4
For case #2
----------------------------------------------#2
435 - 32x = 179. Add 32 x to each side
435 -32x + 32x = 179 + 32x. Subtract 170 from each side
435 -179 = 32x or
32x = 256 or x = 8
