Question

The difference of 2 numbers is 21 and there quotient is 4

Answer 1

Hey! Lets solve this shall we ?

So we must translate this first such that we have

x - y = 21 and (x/y) = 4

Then, we must modify the second equation to get x = 4y by cross multiplication. Next, substitute 4y into the other equation such that

(4y) - y = 21...............Then add like terms such that

3y = 21...............Then divide 3 such that

y = 7

Now, we plug 7 into the first equation such that

x - 7 = 21...............Add 7 to both sides such that

x = 28

I hope this helped!
