Question

Solve
3(n-5) = 21
please solve and write steps

Answer 1

n=12

Explanation:

3(n-5)=21

3×n and 3×-5=21

3n-15=21

3n=21+15

3n=36

n=36÷3

n=12

Answer 2

Explanation:

Distribute the 3 on the left side of the equation:

3n - 15 = 21

Add 15 to both sides of the equation to isolate the term with the variable on one side:

3n - 15 + 15 = 21 + 15

3n = 36

Finally, divide both sides of the equation by 3 to solve for n:

n = 12

Therefore, the solution to the equation 3(n-5) = 21 is n = 12.
