It really does not matter, I tend to solve for x first simply because it comes before y, but you do whatever is easier for you.
Answer:
B.
(3x + 4)(x − 7)
Step-by-step explanation:
If you multiply.
3x2-21x+4x-28
3X2-17x-28
(This is a little difficult but I've got it)
((x - 45)/12) + 20 = 5(32 - x)
(I made the equation a little more complex than I should have but that equation should still work if you were to solve for x)
