Question

Solve this system of equations using the substitution method.
y = 2x
- 3x - 15 = y

Answer 1

x = -3

y = -6

Explanation:

We are given the following system of equations:

y = 2x

-3x - 15 = y

We can use the substitution method to solve this system.

Substitute y = 2x from the first equation into the second equation and solve for x:

-3x - 15 = 2x

-5x = 15

x = -3

Now that we have found x, we can use the first equation to find y:

y = 2x = 2(-3) = -6

Therefore, the solution to the system of equations is (x, y) = (-3, -6).
