Accepted Solution
A:
Hello from MrBillDoesMath!
Answer: Case 1: approximately 429.4, Case 2: 8
Discussion:
Let the unknown be "x". The problem statement could mean either32 * (435 -x) = 179 (#1)or435 - 32*x = 179 (#2)It's unclear which one is wanted so we solve both of them.----------------------------------------------#1But for case #1 32 * (435 -x) = 179 32 * 435 - 32x = 179 or13920 - 32x = 179Add 32x to both sides13920 = 179 + 32xSubtract 179 from both sides:13920 - 179 = 32xDivide both side by x to getx = (13920 -179)/32 = 13741/32 which is approximately 429.4 For case #2----------------------------------------------#2435 - 32x = 179. Add 32 x to each side435 -32x + 32x = 179 + 32x. Subtract 170 from each side435 -179 = 32x or32x = 256 or x = 8 Regards, MrB
