**PsyDAG**, Tuesday, January 29, 2013 at 11:41amProcess: Let S = Susan's current age and K = Karen's

S = K + 9

2/3(S + 10) = K + 10

Substitute K+9 for S in second equation and solve for K. Insert that value into the first equation and solve for S. Check by inserting both values into the second equation. Add 10 to each age.
