Question

Solve, using the substitution method.

y = 4x + 6
5x – y = 6


A.
There are an infinite number of solutions.

B.
There is no solution.

C.
(18, 12)

D.
(12, 54)

Answer 1

y = 4x + 6
-6 -6
y - 6 = 4x
y/4 - 6/4 = 4x/4
y/4 - 1.5 = x

5x – y = 6
5(y/4 - 1.5) - y = 6

Then you can just plug into https://www.desmos.com/calculator and y = 54
then substitute y into either equation and solve for x

Answer 2

y = 4x + 6
54 = 4x + 6
-6 -6
48 = 4x
48/4 = 4x/4
12 = x
So the solution is (12, 54)
