the ages of two brothers are in the ratio two to three,but in eight years the ratio of ther ages will be three to four .findtheir presentage

8 years agohmmmm, so you want to turn this into a series of equations based on the rules outlined in the word problem. and then solve them.

8 years agoso how can you write one of the equations given the first piece of information?

8 years agoe.g. \[y = 2x/3\]

8 years agowhere y = younger, and x = older

8 years agobut since there are two variables in this problem, you need a second equation to solve

8 years ago(the two present ages are the two variables)

8 years agoso we know in 8 years, that the ratio will actually be 3/4, not 2/3

8 years agoso: y+8/x+8 = 3/4

8 years agonow that you have two unknown variables (the present ages), and two equations, you can solve the problem by substituting the first (y=2x/3) into the second.

8 years agothank you :)

8 years agono problem!
