What is the equation 7n + 6n -5 = 4n + 4
2 answers:
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
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! :)
