So, you take one of the variables and get it on the side of the equals sign that doesn't have a variable yet using opposite symbols. Eg, 2x-3y=6 to 2x=6+3y
I honestly can't remember what next-- I'm in 8th grade math too, but that section was a while ago for me.
Oh oh oh oh oh I REMEMBER
Then when you have 2x=6+3y
then
x=3+3y
Nope. Must've done something wrong.
Sorry. I can't remember ANYTHING.... good luck
