Maths help

I'm doing a practice paper and one of the questions is
Solve
6x - 5y = 110
7x 10y = 30
Can someone give me the answer AND explain how they got it because I never understand these question and YouTube isn't helping.

First :Put the first equation into terms of y.

First :Put the first equation into terms of y.

Oh god, this just shows how bad I am at maths : (

why? it's simultaneous equations

so you have these
6x - 5y = 110
7x + 10y = 30

now I would multiply all of 6x - 5y = 110 by 2 then add the two equations together, the y's should cancel out and you can solve for x
then use your value for x and substitute it in to one of the equations to find y

why? it's simultaneous equations

So I've done it and I've looked at the mark scheme to correct my work and the answer is
x= 10
y = 10

Those values don't satisfy the equations you posted originally!

Can you upload a picture of the question?
