Answer:
In the first one, 4 is multiplied by c. In the second one, 1/4 is multiplied by c.
Step-by-step explanation:
Move the 1st equation to get y by itself so it’s now y=-4x so you can substitute that in for the second equation 2y+x=-7 becomes 2(-4x)+x=-7
-8x+x=-7
-7x=-7
x=1
then plug that back in to find y
4(1)+y=0
4+y=0
y=-4
now you have x and y so your coordinate (the answer) is (1, -4) hope this helps!
