Solve 12-3(x-1)=9

Evaluate

12 - 3 (x - 1) = 9

Move the expression to the left side

12 - 3 (x - 1) - 9 = 0

Subtract the numbers

3 - 3 (x - 1) = 0

Calculate

More Steps

6 - 3 x = 0

Move the constant to the right-hand side and change its sign

- 3 x = 0 - 6

Removing 0 doesn't change the value,so remove it from the expression

- 3 x = - 6

Change the signs on both sides of the equation

3 x = 6

Divide both sides

\frac{3 x}{3} = \frac{6}{3}

Divide the numbers

x = \frac{6}{3}
