texaschic101 · Answer

A + J = 425
A = J + 25
now we sub
(J + 25) + J = 425
2J + 25 = 425
2J = 425 - 25
2J = 400
J = 400/2
J = 200

A + J = 425
A + 200 = 425
A = 425 - 200
A = 225

check..
A + J = 425                           A = J + 25                
225 + 200 = 425                  225 = 200 + 25
425 = 425 (correct)               225 = 225 (correct)

therefore, Ann (A) made a score of 225 and Jane (J) made a score of 200....
so that is how it is done...I wanted to show you so you would understand. If you have any questions, please ask :)
