Question

3(x−3)=
21

Answer 1

3(x-3) = 21

First, distribute the 3 on the left side of the equation:

3x - 9 = 21

Now, add 9 to both sides of the equation to isolate the variable:

3x = 30

Finally, divide by 3 to solve for x:

x = 10

Therefore, the solution to the equation 3(x-3) = 21 is x = 10.
