Answer:

Step-by-step explanation: One number is four more than the other."   is represented as 'x'

"One number is four more than the other."  is represented as 'x+4'

"Their sum is fourteen."  is represented as 'x+(x+4)=14'

"Find both numbers."

x+(x+4)=14

x+x+4=14  (add like terms)

2x+4=14 (isolate your 'x' variable on one side of the equality by subtracting 4 from both sides)

2x+4-4=14-4

2x=10 (isolate your 'x' variable by dividing by 2 from both sides)

2x/2=10/2

x=5  (this is the answer to one number)

x+4=5+4=9 (plug in 5 for 'x' and this is the answer to four more than another)

Your two numbers are 5 and 9.
