Answer:

x = 10 and y = 5

Explanation:

We are given:

the system of equations

-4x+11y=15... Equation 1

x=2y....... Equation 2

We substitute 2y for x in Equation 1

-4(2y) + 11y = 15

-8y + 11y = 15

3y = 15

y = 15/3

y = 5

Solving for x

2y = x

2(5) = x

10 = x

Therefore,

x = 10 and y = 5
