Answer:
(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
