7x - y = 10
x - 4y = -14

(2,4)

Step-by-step explanation:

using substitution you can rewrite 7x-y=10 to y=-10+7x

then use that to substitute for the y in the equation x-4y=-14; which gives you the equation; x-4(-10+7x)=-14

which you can then distribute using foil, giving you x=2.

then you can replace any equation's x with 2 to find y,

for example,

7(2)-y=10

then y=4
