Answer:
Step-by-step explanation:
To solve this system of equations, we can start by substituting the second equation into the first equation, to eliminate one of the variables.
Substituting x = 2y into the first equation gives us:
-4(2y) + 11y = 15
Simplifying this equation gives us:
-8y + 11y = 15
Combining like terms, we get:
3y = 15
Dividing both sides by 3, we get:
y = 5
Substituting this value back into the second equation gives us:
x = 2(5)
Simplifying this equation gives us:
x = 10
So the solution to the system of equations is x = 10 and y = 5.
