Question

What is the solution to the system of equations?

Answer 1

Answer:

The solution would be (-19, 40)

Step-by-step explanation:

In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.

5x + 2y = 15

5x + 2(-3x - 2) = 15

5x - 6x - 4 = 15

-x - 4 = 15

-x = 19

x = -19

Now that we have the value of x, we can find the value of y.

y = -3x - 3

y = -3(-19) - 3

y = 43 - 3

y = 40
