Age Practice problem

Question

The sum of the ages of Spencer and Jasmine is 91 years. 8 years ago, Spencer's age was 4 times Jasmine's age. How old is Spencer now?

Answer 1

S + J = 91

S-8 = 4(J-8) = 4J-32

S = 4J-24

S=91-J = 4J-24

5J =91+24 = 115

J = 115/5 = 23

S=91-23 = 68 years old now for Spencer
