Question

What is the equation 7n + 6n -5 = 4n + 4

Answer 1

Hi there!

So you need to put all the same terms together so that your equation can be simplified :

7n + 6n -5 = 4n + 4

7n + 6n = 13n

13n - 5 = 4n + 4

Subtract 4n from each side of the equation

9n -5 = 4

Add 5 on each side of the equation

9n = 9

Divide each side of the equation by 9

n = 1

There you go! I really hope this helped, if there's anything just let me know! :)

Answer 2

7n + 6n -5 = 4n + 4

combine like terms

13n-5 = 4n+4

subtract 4n from each side

9n -5 = 4

add 5 to each side

9n = 9

divide by 9

n =1
