Question

One number is 4 more than 3 times another. Their sum is 28. Find the two numbers.

Answer 1

Ev,

Let n = first number, then

28-n is the second number since they add up to 28

 

n = 3*(28-n) + 4 represents the condition in your first sentence

So n = 84 - 3n + 4

or 4n = 88  and n = 22, and 28-n = 6

So the 2 numbers are 22 and 6

 

CHECK first sentence 3*6 + 4 = 18 + 4 = 22  OK!
