Let X be the present age of the student X+15 is the present age of the teacher After 15 years: (You need to add 15 to both of their ages) student: x+15 teacher: (x+15)+15 or x+30

Note: Remember that ratio can also be expressed in the form of fraction

Equation:

x+30 3 ------- = --- cross multiply x+15 2

2x+60=3x+45 combine like terms (transpose 45 to the other side of the equation same for 2x) Note: ( If you are transferring numbers the sign will become the opposite. Thus 45 will be -45 and 2x will be -2x
