Help and explain please!

Help and explain please! 2x+3y=12

Help and explain please! 2x+3y=12Solve for y.

2x + 3y = 12

so basically we want to get y by its self.

first were going to get y on the left side and everything else on the right. in order to do that we have to subtract 2x from the left and do the same on the other side.

2x + 3y=12

-2x.-2x

3y = 12 -2x

then we divide everything by 3 on the other side to get y by its self.

3y = 12-2x

---.

3.3.3

y= 4 -2/3x

should be your answer.

Hope this helps, have a great day!
