Solving simultaneous equations

Hello

How do you solve the following simultaneous equations? (do you solve it by elimination method or subtitution method)

2y + x = 10 and x= 3 + 5y

Thank you

Re: Solving simultaneous equations

Hi Greaterpathmagician;

2y+x=10
2y+3+5y=10
y=1
x=8

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Solving simultaneous equations

that one is easily solved by substitution. x is already given for you.
