Answer: x = 17
Step-by-step explanation: combine all of those numbers.
3x+x+22.
Combine like terms, so
4x + 22 = 90 (90 is the sum of 2 complementary angles)
Subtract 22 from both sides to get
4x = 68
Now divide by 4 to get x which is
x = 17
Expand
12x - 48 + 4x + 28
Collect like terms
(12x + 4x) + (-48 + 28)
Simplify
<u>16x - 20</u>
