Answer:

n = 3

Explanation:

Distribute 6 into 2n+5, which is 12n +30

Subtract 30 from 66, which is 36

Divide 36 by 12

You're left with n = 3

Or in numbers:

6(2n+5)=66

12n+30=66

12n=36

n=3

Answer:

n=3

Explanation:

Step 1: Simplify both sides of the equation.

6(2n+5)=66

(6)(2n)+(6)(5)=66(Distribute)

12n+30=66

Step 2: Subtract 30 from both sides.

12n+30−30=66−30

12n=36

Step 3: Divide both sides by 12.

12n/12 = 36/12

n=3
