    Pretend y is x.

    It's just a different variable.

    combine like terms, add 2 to both sides to get the y alone, divide by 4

    Unless, however, the problem is parametric, in which case the equation is used to find the y coordinate. The x equation is treated the same way.

    Can you type out the whole process for me to see?

    \[Y-2+3Y=10\] \[Y+3y=10-2=8\] \[4y=8\] \[Y=8div4\] \[Y=2\]

    Does that make sense?

    I have to look it over before I can say whether or not it makes sense.

    So the Y is equal to 1 that made it 4?

    No, it equals 2.

    In order for the equation to hold true.

    No,what I meant was : Y+ 3y = 4?

    No, y+3y=8 because you subtract 2 from 10 first, getting 8. So, y+3y=8 Which then becomes 4y because you add the y's together, or combine like terms. Then you get y=2, because you divide 8 by 4.
