Solve:
12y%2B7+=+21y First, collect the y's on one side of the equation by subtracting 12y from both sides.
12y-12y%2B7+=+21y-12y Evaluate this.
7+=+9y Now divide both sides by 9 to get the y by itself.
7%2F9+=+cross%289%29y%2Fcross%289%29 Cancel the 9's on the right side.
7%2F9+=+y or highlight%28y+=+7%2F9%29

12y + 7 = 21

12y = 14 ------ Subtracting 7 from each side of equation

y = 14%2F12, or 1%262%2F12, or highlight_green%281%261%2F6%29
