Lauren had 1/5 as many seashells as Adam. Adam gave 22 seashells to Lauren so that they would each have the same amount. How many seashells did the two friends have altogether?
+36916 Given L = 1/5 A
then Adam gives 22
L + 22 = A - 22 sub in the red equation
1/5 A + 22 = A - 22
A = 55 L = 1/5 A = 11 Total = 66 shells
