Hello,

What is the value of x that satisfies the following simultaneous equation:

x - y = - 2

5x + 8y = - 23

I have never been excellent at maths. So this might be the simplest simultaneous equation for you but for me I have no clue. I did do some prior research (again might sound like a dummy) and here's what I got on how to solve it:

5x + 8(x+-2) = -23

5x + 8x+-16 = -23

13 + -16 = - 23

13x + 16 = -23

5x = - 23

Please help!
