Question

Emily and Jasmine had the same number of stamps. After Emily gave 42 stamps to Jasmine, Jasmine had twice as many stamps as Emily. How many stamps did Jasmine have in the end?

Answer 1

2(e - 42) = j + 42

 

Since e = j, we can use j in place of e.

 

2(j - 42) = j + 42

2j - 84 = j + 42

j = 126

 

126 + 42 = 208
