Question

Robin had 6 pairs of shoes. Rhonda borrowed x pairs of shoes from Robin, and then Robin had 4 pairs left. Which equation models this situation?

Answer 1

A word problem is given, it is required to find the equation that models the situation.

Since Robin has 6 pairs and Rhonda borrowed x pairs, the expression for this can be written by subtracting x from 6:

`6-x`

Note that this expression gives the number of pairs Robin will have left.

Since it is given that Robin had 4 pairs left, equate the expression to 4:

`6-x=4`

Hence, the required expression is 6-x=4.
