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

A MOSTLY

Answer 2

Input in standard form the equation of the given line.

The line with m = 1/2 and b = 3.

Answer 3

Say we have 2 numbers, x and y. So we know one number is 3 less then than twice another so:

y= 2x-3

And we know that both numbers need to have a sum of 39 (AKA add up to 39)

So x+y=39
