I'll try my best to answer this question to the best of my abilities.

3x+y=5
3x+(2x)=5
5x=5
x=1

Thank you
I was uncertain of the order of operation
Oh. Well, no problem then.
that is only subsitution

subsitution means subsituteing something for another and getting the answer
the way to do this is to get an easy equation and make it equal to only one placeholder so
y=2x
so you can subsitute y for 2x anywhere you see a y
3x+y=5
subsitutute
3x+2x=5
5x=5
divide both sides by 5
x=1
subsitute
y=2(1)
y=2

elimination is when you elimintate one of the terms by adding the equations together and canceling som of them out
so y=2x
subtract y from both sides
0=2x-y or 2x-y=0

add this to the second equation
3x+2x+y-y=0+5
5x=5
divide both sides by 5
x=1
subsitute
y=2(1)
y=2

x=1
y=2
