Question

10y-11x=-4 -2y+3x=4

I need to know what x and y equal

Answer 1

Explanation:

`10y - 11x = -4`

`-2y + 3x = 4`

One way to solve a system of equations is to make it so both equations have a similar coefficient for one of the
`x` or
`y` terms. In this case, it's easiest to multiply the second equation by
`5` so there's a
`10y` in both equations:

`10y - 11x = -4`

`-10y + 15x = 20`

Now, we can add the two equations together to get rid of the
`y` variable and solve for
`x`:

`(10y - 11x) + (-10y + 15x) = -4 + 20`

`(10y - 10y) + (-11x + 15x) = 16`

`4x = 16`

`x = 4`

Now that we know the value of
`x`, we can plug it back into one of the original equations to solve for
`y`:

`10y - 11x = -4`

`10y - 11(4) = -4`

`10y - 44 = -4`

`10y = 40`

`y = 4`

Therefore, the solution to this problem is
`(4, 4)`
