Question

Variable g is 8 more than variable w. Variable g is also 2 less than w. Which of the following pairs of equations best models the relationship between g and w?

g = 8w
g = w + 2

w = g + 8
w = g − 2

w = 8g
w = g + 2

g = w + 8
g = w − 2

Answer 1

If you would like to find a pair of equations that best models the relationship between g and w, you can do this using the following steps:

g is 8 more than w ... g = w + 8
g is 2 less than w ... g = w - 2

The correct result would be g = w + 8 and g = w - 2.
