Question 82152: OK, the problem is: Solve the system of equations using the substitution method.
If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is “no solution” or “infinitely many solutions.”
-7x + y = 4
2x + 8y = 0
my understanding is; I should first solve the top equation because the y has a coefficient of 1 (not sure why, but that's my guess) when I do this I get:
x = -(-y+4/7) and then I am lost . . .
