Answer:
Step-by-step explanation:
2x-5y=20
Making y the subject
-5y = -2x + 20
Dividing by -5
y = -2/-5x + 20/-5
y = 2/5x - 4
So comparing with y = mx + c
Slope m = 2/5
Intercept c = -4
K-3 should be the answer because andrew has 3 less than Paul.
Do 360/5 and you will get your answer
6x - 5y = 17
7x + 3y = 11
to eliminate x....there is a couple ways to do this...
u can multiply equation 1 by 7 and equation 2 by -6
