Two numbers are in the ratio 4:7.If thrice the larger is added to twice the smaller ,we get 87.Find the numbers

Set up your question
x/y = 4/7 : 4y= 7x
let x be larger than y
3x + 2y = 87
Substitute the value of x in the equation above and solve for y 
simple way ...
let the two numbers be 4x and 7x
3(7x) + 2(4x) = 87
29x=87
x = 3
numbers are 12 and 21
