<span>4( n + 1) = 8
</span><span>
First, apply the distributive property.

4*n = 4n
4*1 = 4

4n + 4 = 8

Now, subtract to isolate the variable. 

4n + 4 = 8
     -4     -4

4n = 8 -4
4n = 4

4n/4 = 4/4
n = 1

Final answer: n = 1

Check our work! :D

4(1 + 1) = 8
4*1 = 4
4*1 = 4

4+4 = 8
8=8

CORRECT ANSWER: n = 1

a football game has 13 fans for every 7 players. if there are 540 more fans than players. how many players are there
Mademuasel [1]
For this problem, we can set up an equation. We will represent how many players there are as x. This is what our equation would look like:

13/7 = 540/x

Now we can multiply both sides by x:

13x/7 = 540

Now we multiply both sides by 7:

13x = 91

Now we simplify and divide 13 from both sides to get our final answer:

x = 7
