3y = -2x + 2
y = x + 4 (Substitute the y)
3(x + 4) = -2x + 2 (Distribute)
3x + 12 = -2x + 2 (Add 3 to both sides)
+3x +3x
------------------------------------------
12 = 1x + 2 (Subtract 2 from both sides)
-2 - 2
------------------------
10 = 1x (Divide by 1 on both sides)
10/1 = 1x/1
x = 10
This is your x-coordinate
8/20 of a minute or 2/5 of a minute
5 equals 5/1. Simple as that.
By replacing you get:
5*7-2*11+3*(-1) = 35-22-3= 10
so the answer is 10.
