One number is 8 less than another number. The sum of the numbers is 80. Find both numbers

Answer 1

Greetings! Lets solve this shall we ?

So, we must find two numbers x and y such that

y = x - 8 and x + y = 80...........We substitute the x - 8 into the second equation such that

x + (x - 8) = 80................Add like terms such that

2x - 8 = 80............Add 8 such that

2x = 88.............Divide 2 such that

x = 44

Then we plug 44 into the second equation such that

y = 44 - 8

y = 36

I hope this helped!
