Jessie = Todd + 6 
Todd = Ryan -2 
if Ryan = r
so Todd = r-2 
then Jessie = (r-2) + 6 = r-4 years old

Turn 7 into a fraction so it can be multiplied. > 7/1
Multiply 7/1 by 1/3.
7/1 × 1/3 = 7/3
Simplify 7/3 into a mixed number.
7/3 = 2 1/3

The elimination method is a sufficient way to solve problems. 
2x+y= 20
6x-5y=12
Add 5y to the one equation.
2x+6y= 20
6x= 12
Subtract 2x from both sides. 
6y= 20
4x= 12
Divide 6 by 20. 
y= 3.3 
Divide 4 by 12.
x= 3
I hope this helped you!
