To solve the equation $-3x+9=0$, we need to isolate the variable $x$.<br /><br />Step 1: Add $3x$ to both sides of the equation to move the $-3x$ term to the other side.<br />$-3x+9+3x=0+3x$<br />$9=3x$<br /><br />Step 2: Divide both sides of the equation by $3$ to solve for $x$.<br />$\frac{9}{3}=\frac{3x}{3}$<br />$3=x$<br /><br />Therefore, the solution to the equation $-3x+9=0$ is $x=3$.
