aum · Answer

Chris is 2, Jenny is 4.
After "x" years, Chris will be (x+2) and Jenny will be (4+x)
"... in how many years will jen be 7 years younger than twice Chris's age?"
4+x = 2(x+2) - 7
4+x = 2x + 4 - 7
x = 2x - 7
x = 7

aum · Answer

To check if this is correct, after 7 years, Chris will be 9, Jenny will be 11
11 = 2*9 - 7  which is true.
