what is the solution to inequality of [9n-9]+10=7​

Answer:

STEPS:

9n-9+10=7: n= 2/3

Remove the parentheses: (a)=a

9n-9+10=7

add/subtract the numbers: -9+10=1

9n+1=7

subtract 1 from both sides:

9n+1-1=7-1

simplify:

9n=6

divide both sides by 9

9n/9=6/9

simplify:

n=2/3

Answer:

n = 2/3

Explanation:

[9n-9]+10=7​

Subtract 10 from each side

9n -9+10-10 =7-10

9n -9 = -3

Add 9 to each side

9n -9+9 = -3+9

9n = 6

Divide by 9

9n/9 = 6/9

n = 2/3
