Solve the system of equations using substitution. 4x - y = 7
3y – 12x = -21
(3,5)
(6, 17)
no solution
infinite solutions

Infinite amount of solutions

Step-by-step explanation:

Step 1: Write systems of equations

4x - y = 7

3y - 12x = -21

Step 2: Rewrite

-y = 7 - 4x

y = 4x - 7

Step 3: Solve for x

Here we see that we would have infinite amount of solutions.
