Question

How do you solve the system -11x-10y=17 and 5x-7y=50?

Answer 1

First multiply the second equation with 11/5 then solve it accordingly `(x=-6.09)`.

Explanation:

When you multiply the second equation with 2.2 (which is 11/5) and then combine the equations, you will get `y=-5`.

Then you can finally solve x either using the first equation or using the second. Let me start with the first equation:

`-11x - 10*-5 = 17`

`-11x - 50 = 17`

`-11x = 67`

`x=-6.09`
