Sissy · Answer 1

Jason = 20yrs. old

Mandy = 15yrs. old

Explanation:

Let

J = Jason's age

M = Mandy's age

J+M=35 ... eq. 1

J-10=2 (M-10) ... eq. 2

From eq. 1

J=35-M

Substitute this in eq. 2.

(35-M) - 10=2 (M-10)

35-10-M=2M-20

35-10+20=2M+M

45=3M

453 = 3M 3

15=M

J=35-M

J=35-15

J = 20
