Solve the system of equations 3x + y = 3 and 7x + 2y = 1

x=-5 and y=18

Step-by-step explanation:You multiply 3x+y=3 by 2 to get 6x+2y=6. Then, you subtract 6x+2y=6 from 7x+2y=1. The result is x=-5. You then plug -5 into an x in one of the equations and get y equal to 18.

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
