Question

Solve the system of equations.​

Answer 1

x = 10, y = 5

Explanation:

Substitute the second equation into the x value of the first equation.

-4x + 11y = 15

-4(2y) + 11y = 15

-8y + 11y = 15

3y = 15

y = 5

Now substitute the y value into an original equation.

x = 2y

x = 2(5)

x = 10
