Question

​ Solve System Of Equation −4x+11y=15 x=2y ​ x= y=

Answer 1

Answer:

y=5 x=110

Step-by-step explanation:

Answer 2

Answer:

x = 10 , y = 5

Step-by-step explanation:

It is given that x = 2y. Plug in 2y for x in the first equation, and then solve for the variable, y:

-4x  + 11y = 15

x = 2y

-4(2y) + 11y = 15

First, multiply, then combine like terms:

(-4 * 2y) + 11y = 15

(-8y) + 11y = 15

11y - 8y = 15

3y = 15

Isolate the variable, y. Divide 3 from both sides of the equations:

(3y)/3 = (15)/3

y = 15/3 = 5

Plug in 5 for y in one of the equations to solve for x:

x = 2y

x = 2(5)

x = 10

x = 10 , y = 5
