one method for solving 3(x-4)=18 is to first

1 answer

distribute the 3 to the terms inside the parentheses.

The equation becomes 3x - 12 = 18.

Next, add 12 to both sides of the equation to isolate the x-term.

3x - 12 + 12 = 18 + 12

Simplifying the left side of the equation gives 3x = 30.

Finally, divide both sides of the equation by 3 to solve for x.

3x/3 = 30/3

This gives the solution x = 10.
