Joey is 17 years older than his sister Pat. In 6 years, Joey will be 7 more than twice Pat’s age then. How old are Joey and Pat today?

Answer 1

Joey is 21; Pat is 4

Explanation:

The problem statement supports two equations in Joey's age (j) and Pat's age (p):

j - p = 17

(j +6) -2(p +6) = 7

Subtracting the second equation from the first, we have ...

(j -p) -((j +6) -2(p +6)) = (17) -(7)

p +6 = 10 . . . . . simplify

p = 4 . . . . . . . . . subtract 6

J = 17 +4 = 21

Joey is 21; Pat is 4.

Answer 2

p = 4

j = 21

Explanation:

Joey = j

Pat = p

j = p + 17

(j+6) = 2*(p + 6) + 7 Simplify this. Remove the brackets.

j + 6 = 2p + 12 + 7 combine like terms

j + 6 = 2p + 19 Subtract 6 from both sides

j +6-6 = 2p +19-6

j = 2p + 13

================

Equation j = 2p + 13 and j = p + 17

2p + 13 = p + 17 Subtract p from both sides

2p-p+13 =p-p + 17

p + 13 = 17 Subtract 13 from both sides

p = 17-13

p = 4

============

j = p + 17

j = 4 + 17

j = 21
