Question

How do you solve the system of equations `9x + 3y = - 18` and `3x - 5y = - 24`?

Answer 1

x=-3
y=3

Explanation:

= `9x+3y=-18`
Divide 3 on both sides

= `3x+y=-6`

Now Subtracting

=`(3x+y=-6)-(3x-5y=-24)`

= `6y=18`

= `y=3`

For `x` doing putting in following

=`3x-5y=-24`

= `3x-5(3)=-24`

= `3x=-9`

= `x=-3`
