Two equations are given below:
1 answer:
You can fill the second in in the first to get an equation with only b:
(b-2) - 3b = 22 =>
-4b-2 = 22 =>
-4b = 24
b = -6
a = -6-2 = -8
So (-8,-6) is the answer.

I just multiplied the total by the refund percentage to get that number. It’s just like finding a tip.
8x10 = 80
4x4 = 16
2x4 divided 2 = 4
80+16+ 4 = 100
18 km apart
You subtract 33 and 15
A:B = 2:3
A=126
B=?
126/2=63
63x3=189
A=126
B=189
A:B = 126:189
Answer:
B and is (-2, 3)...........
