well, how old will John be in five years?
Mary will be twice that.
So subtract 5 years to get her current age.
or, doing the math by the book,
J = 10
M+5 = 2(J+5)
Mary will be twice that.
So subtract 5 years to get her current age.
or, doing the math by the book,
J = 10
M+5 = 2(J+5)

10-5=5
Mary age=5
10×5=50
50-20=30
Mary age in five years time=30
Mary's current age=27
Mary age=5
10×5=50
50-20=30
Mary age in five years time=30
Mary's current age=27

Answer is 20 because the equation is 10 + 5 x 2 so you would use bomdas and multiply would be first so 10+ 10 = 20 Simple
