Question

2x-5y=20
What is y and what is x

Answer 1

x=10 and y=4

Im not sure if this is correct but I looked it up and it said it was right

Answer 2

• x = 5/2y + 10
• y = 2/5x - 4

(if you're looking for intercepts then: x = 10, y = -4)

Explanation:

`\sf{2x - 5y = 20`

`\sf{Finding~x:`

`2x - 5y = 20`

`+ 5y = + 5y`

↪ 2x = 5y + 20

`(2x)/(2) = (5y)/(2) + (20)/(2)`

x = 5/2y + 10

`\sf{Finding~y:}`

`2x - 5y = 20`

`-2x~ = ~~~~-2x`

↪ -5y = -2x + 20

`(-5y)/(-5) = (-2x)/(-5) + (20)/(-5)`

y = 2/5x - 4

Hope this helps!
