can someone help me solve this? not just an answer but a method of solving cause im having a hard time grasping this.
Three times the larger of two numbers is equal to four times the smaller. The sum of the numbers is 21. Find the numbers.

3xy = 4y
x+y = 21
let x equal the larger number
let y equal the smaller number
ok..
take it step by step. u first divide 4y on both sides. if that doesn't work, just plug numbers in. hope this helps! please answer my question! thanks.

Three times the larger of two numbers is equal to four times the smaller. Let x equal the larger number, and
let y equal the smaller number.
3x = 4y or dividing both sides by 4, y = 3/4x
The sum of the numbers is 21.
x + y = 21
Substitute 3/4x for y in the second equation. and solve for x. Put that value into the first equation to find y. Check by putting both values into the second equation.
I hope this helps a little more. Thanks for asking.
