Question 1088348

Shania is 4 times as old as Jenny. Jenny is 3 years older than Enrique. If their total age is 57, how old will Jenny be in four years ?

I tried the following:

S = 4x
J = x +3
E = x

4x+x+3+x=57

not sure how to continue from here...
thank you
<pre>It's very, very SIMPLE. You just need 1 (ONE) variable.
Let Jenny's age be J
Then Shania's is 4J, and Enrique's is: J - 3
We then get: J + 4J + J - 3 = 57
6J = 57 + 3
6J = 60
J, or Jenny is: {{{matrix(1,4, 60/6, or, 10, years-old)}}}
So, in 4 (four) years, Jenny will be: {{{highlight_green(matrix(1,4, "10 + 4,", or, 14, years-old))}}}
