Question

The varsity football team consists of seniors and juniors. The number of seniors is 7 less than the number of juniors. There are 43 members on the team.

Answer 1

There are 18 seniors and 25 juniors.

Explanation:

• Find your equation. For this equation, it comes out to be:

x + x + 7= 43 or 2x+7=43

X represents the amount of seniors.

The amount of juniors can be represented as x+7

• Solve the equation. It comes out to be:

1st - Transfer the 7 to the other side to get the x by itself

2x=36

2nd - Divide 36 by 2 to leave x by itself

x=18

• Answer the question. Because you didn't specify what your were asking for, I imagine it's the number of player from each class.

Because x represents the seniors, there are 18 seniors.

There are 7 more juniors, add 7 to 18, so there's 25.
