Question

How do you solve the following system?: `2x+5=-9y , 6x -12 = -3y`

Answer 1

There are 3 *methods* to solve it. I am using substitution method.

Explanation:

This is how we do this:
`x=(-9y-5)/2` ( From equation 1)
putting the value of `x` in equation 2
`6(-9y-5)/2 - 12= -3y`

`-27y-15-12=-3y`

`-27 = 24y`

`y= -27/24`
`therefore y=-9/8`

Now put the value of `'y'`in the first equation to get the value of `'x'`
`Hence` `solved.`
