Question 511218: "The ratio of my age to my mother's age today is 3:5.
In five years time the ratio will be 7:11.
Let x be the sum of our ages today.
Set up a linear equation and use it to find our ages in five years.
Start the equation like this:
3x/8+5 =..."
I have started the linear equation but do not know how to continue it. This is all I have so far:
3x/8+5 = 7/18(x+10)

---
Your age now: 3x
Mother's age now: 5x
---
Equation:
(3x+5)/(5x+5) = 7/11
---
11(3x+5) = 7(5x+5)
33x + 55 = 35x + 35
2x = 20
x = 10
---
Now Ages:
Your age now = 3x = 30
Mother's age now = 5x = 50
