I dont know how solve this problem:
Solve 4y+1=2y+8
our objective here, is to get y on one side of the equal sign by itself. whatever we don't want on one side, we subtract it from both sides of the equation. so let's do that.
Let's get the y's on the left side. so i want to get rid of the 2y on the right, so subtract it from both sides.
Now let's get rid of the 1 on the left side
Now divide both sides by 2
remember, the objective was to get y only on one side. at the end i had 2y, i needed to have only y. when i divided by 2, it canceled the 2 that was beside the y, so i was left with y on one side, like i wanted. but since it is an equation, whatever i do on one side, i have to do on the other to keep things equal. so i divided by 2 on the right side as well to get 7/2
