# Simultaneous Equations Help watch

1. I'm having some trouble solving these simultaneous equations:

2x-y=6
4x+3y=22

Could someone please try and help me solve them by elimination as when I work it out I get a completely different answer to what is in the back of the book. Thank you

What have you tried??
3. 2x-y=6 can be rearranged to y=2x-6
So if you know what y is equal to, you can substitute it into the second equation so you get:
4x+3(2x-6)=22
Expand out the bracket and rearrange to solve for x. Once you know the value for x, you can substitute it back into any of the equations to find y

4. You're welcome
