Question

Please please helpppp.

Answer 1

There are 3 ways of solving a simultaneous problem, substitution method, elimination method and Gauss-Jordan method. I'm gonna use the substitution method since it's easier and i think it would suit your level more.

First let's try solving for y since it's easier to start with.

Firstly we have to find an equation for x:

`x-2y=2\\x-2y+2y=2+2y\\x=2+2y`

Great, now we can use the substitution method to find the value of y using the first equation:

`2x+3y=11\\2(2+2y)+3y=11\\4+4y+3y=11\\7y=7\\y=1`

Now we know that y=1 we can solve the first equation we made:

`x=2+2y\\x=2+2(1)\\x=4`

And the answer is
`x=4 , y= 1\\(4,1)`

Double check:

`2x+3y=11\\2(4)+3(1)=11\\8+3=11\\11=11\\\\x-2y=2\\(4)-2(1)=2\\2=2`

And that's our final answer! (4,1)
