Solve the system by substitution.

Question

y, equals, x
y=
x
minus, 2, x, plus, 4, y, equals, 16
−2x+4y=
16

Answer 1

Since y = x, we can substitute x for y in the second equation:

-2x + 4(x) = 16
-2x + 4x = 16
2x = 16
x = 8

Now that we have found the value of x, we can substitute it back into the first equation to find the value of y:

y = x
y = 8

Therefore, the solution to the system of equations is x = 8 and y = 8.
