Question

How do you solve `2y = 4x - 16` and `5y = 4x + 8`?

Answer 1

Okay we will solve this step by step

Let `2y=4x-16` be equation number 1
and `5y=4x+8` be equation number 2

`4x` is same in both equations that is to say has same coefficient `4x`

So we will subtract both of them
`+5y=+4x+8`
`-2y=-4x +16`
This results in
`3y=24`
`y=8` Substituting this value in equation number 2

`5(8)=4x+8`
`40=4x+8`
`40-8=4x`
`32=4x`
`32/4=x`
`8=x`

So we get `x=8` and `y=8`
