Friends

James and Jerry are friends. Together they have 48 toy cars. If James takes eight cars from Jerry, Jerry would have 1.5 times as many toy cars as James. How many toy cars does each one have?

Final Answer:

a =  16
b =  32

Step-by-step explanation:


a+b=48
b-8 = 1.5 a

a+b=48
b-8 = 1.5·a

a+b = 48
1.5a-b = -8

Pivot: Row 1 ↔ Row 2
1.5a-b = -8
a+b = 48

Row 2 - 1/1.5 · Row 1 → Row 2
1.5a-b = -8
1.67b = 53.33


b = 53.33333333/1.66666667 = 32
a = -8+b/1.5 = -8+32/1.5 = 16

a = 16
b = 32
