How to solve 2x + 9 = 0; x = 2

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

$$2x+9=0; x=2$$

$y = -\frac{9}{2} = -4\frac{1}{2} = -4.5$

Consider the first equation. Subtract $9$ from both sides. Anything subtracted from zero gives its negation.

$$2x=-9$$

Divide both sides by $2$.

$$x=-\frac{9}{2}$$

Consider the second equation. Insert the known values of variables into the equation.

$$y=-\frac{9}{2}$$

The system is now solved.

$$x=-\frac{9}{2}$$ $$y=-\frac{9}{2}$$
