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
