You can put this solution on YOUR website! Let A = the amount Amy has and M = Maria's amount.
A = M-$8 "Amy has $8 less than Maria" Substitue this into the second equation.
A+M = $30 "Together they have $30."
(M-$8)+M = $30 Simplify.
2M-$8 = $30 Add $8 to both sides.
2M = $38 Divide both sides by 2.
M = $19 ...and...
A = M-$8
A = $19-$8
A = $11
Amy has $11 and Maria has $19.
