Solve 9-3x - ScanMath

Evaluate

9 - 3 x

To find the roots of the expression,set the expression equal to 0

9 - 3 x = 0

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

- 3 x = 0 - 9

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

- 3 x = - 9

Change the signs on both sides of the equation

3 x = 9

Divide both sides

\frac{3 x}{3} = \frac{9}{3}

Divide the numbers

x = \frac{9}{3}
