Question

The variables x and y are related proportionally. When x=12, y=8. Find x then y=12.

Answer 1

I don't know if this is correct..
warning: I may be wrong

so you have to do a proportion..

it's easy!

x1/y1 = x2/y2

so, plug in the values!

12/8 = x/12

now solve for x.

cross multiply:
8x = 144
divide by 8:
x = 18

there!
