A problem states: "There are 7 more girls than boys in a club. There are 23 members in the club in all. How many girls are there in the club?"

Let g represent the number of girls.

Which expression represents the number of boys?

7−g
g−7
g⋅7
g + 7

g - 7 represents the number of boys.

Step-by-step explanation:

Let's say that x is the number of boys then:

x + 7 = g

So to find the number of boys we rearrange the equation to make x the subject of the formula:

g - 7 = x + 7 - 7

g - 7 = x

So the number of boys in g - 7
