Question

One number is 3 less than twice another. If their sum is 39, find the numbers.
Which of the following systems of equations represents the word problem?

A) y=2x-3 and y=x+39
B) y=2x-3 and x+y=39
C) y=2(x-3) and x+y=39

Answer 1

Based on the given information, we know that x+y=39

Let "one number" be y
Let the other number be x
This would mean y=2x-3
2x="two times the other number"
-3= "three less"

The correct answer:
B) y=2x-3 and x+y=39

Answer 2

the answer to that is

B.y=2x-3 and x+y=39
