Question

Use the substitution method to solve the system of equations.

{y=3x−7

15x−5y=14

What is the solution?


The solution is (15, 5).

The solution is (0, 7).

There is no solution.

There are an infinite number of solutions.

Answer 1

Insert 3x - 7 for y in 15x - 5y = 14
15x - 5(3x - 7) = 14
15x - 15x + 35 = 14
0 = -21
There is no solution.
