Question

$$y+18=-y-3$$

Solve for y

$y = -\frac{21}{2} = -10\frac{1}{2} = -10.5$

Steps for Solving Linear Equation

Add $y$ to both sides.

$$y+18+y=-3$$

Combine $y$ and $y$ to get $2y$.

$$2y+18=-3$$

Subtract $18$ from both sides.

$$2y=-3-18$$

Subtract $18$ from $-3$ to get $-21$.

$$2y=-21$$

Divide both sides by $2$.

$$y=\frac{-21}{2}$$

Fraction $\frac{-21}{2}$ can be rewritten as $-\frac{21}{2}$ by extracting the negative sign.

$$y=-\frac{21}{2}$$
