Answer:

x = - (15 - 11y)/4

y = x/2

Step by step explanation:Let's first solve for x

=>- 4x + 11y = 15

=>- 4x + 11y - 11y = 15 - 11y

=>- 4x = 15 - 11y

=>(- 4x)/- 4 = 15/- 4 - (11y)/- 4

x = - (15 - 11y)/4

let's solve for y

=>x = 2y

=>2y = x

=>(2y)/2 = x/2

y = x/2

Answer:

  • x = 10
  • y = 5

Step-by-step explanation:

Given system:

  • - 4x + 11y = 15
  • x = 2y

Solve by substitution:

  • - 4(2y) + 11y = 15
  • - 8y + 11y = 15
  • 3y = 15
  • y = 5

Find x:

  • x = 2*5 = 10
