Question 114144: please help me with this problem, i try to solve it by studying your examples, but i really can't get it right...here's the problem:
PERLA IS NOW 5 TIMES AS OLD AS MARILOU. IN 10 YEARS, PERLA WILL BE 3 TIMES AS OLD AS MARILOU. HOW OLD IS EACH? Kindly solve and show the solution. Below is my attempt to solve it. But I guess, its wrong.
Here's my attempt:
let P be Perla's age and M be Marilou's age
a) P = 5M
b) P+10 = 3M
then substirute all the Ps to Ms
b) P + 10 = 3M
5M +10 = 3M
5M - 3M = -10
this is how far as i've gone...it seems that this is wrong since there is a negative number.. Please help me. Thank you.

3. Elizabeth is forty-one years older than Kevin.
4. The sum of of the ages of Elizabeth and Kevin is sixty-seven.

This is how far my mom and I got on this question:
1. 4a - 73 a=Alexander
2. e - 63 b=Eric
3. d + 41 c=Elizabeth
4. c + d = 67 d=Kevin
5. 3a - 16 e=Jonathan
3. 41 + 34 = 75
4. 34 + 33 = 67
My mom and I would appreciate any help with this problem. Thank you for taking the time out to help us.
