Answer 2

So simplify both sides of the equation 4n−7=9
Then add 7 to both sides.
4n−7+7=9+7
4n=16
Step 3: Divide both sides by 4.
4n/4=16/4

Answer 3

-7 + 4n = 9
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + 4n = 9 + 7
Combine like terms: -7 + 7 = 0
0 + 4n = 9 + 7
4n = 9 + 7
Combine like terms: 9 + 7 = 16
4n = 16
Divide each side by '4'.
n = 4
