1/5 of Heidi's savings was equal to 3/7 of Joseph's savings. After Heidi spent $356 and Joseph saved an additional $428; they had an equal amount of money in their savings. How much did Heidi and Joseph save altogether in the end?

Initially

1/5 h = 3/7 j     re-arrange

h = 15/7 j

 

then

 

h -356 = j+428      sub in the red equation for h

15/7 j -356 = j+428        then you can solve for j      use this value to solve for h  

                                           then  subtract 356 from h  and add 428 to j ( the results should be the same)     and add them together.....
