Can someone explain this? I´m still confused 2 + 2y = –y − 10

2+2y=-y-10

2y+y=-10-2

3y=-12

y=-4

So y is the variable, so first step is isolating the variables meaning all the "y"s on one side of the equal sign and the numbers on the other side. After you isolate the variable, you can just do the addition/subtraction/multiplication/division.

Hope this helps!
