W = 17/13.
I hope this helps. I'm pretty sure I got it wrong, but just let me know.
step 1: open up the brackets ( rmb to flip the signs )
step 2: bring 'a' to one side and the numbers to the other
6a + 34 = -3(-2a + 8)
6a + 34 = 6a - 24
6a - 6a = -24 - 34
0 = - 58
the final ans is kind of weird but here's my solution :))
198 = 5X:X = A:B
198 = 5X + X = 6X
X = 198 / 6 = 33
A = 33*5 = 165mph
B = 33*1 = 33mph
