Question

$$3(9)+4y=12$$

Solve for y

$y = -\frac{15}{4} = -3\frac{3}{4} = -3.75$

Steps for Solving Linear Equation

Multiply $3$ and $9$ to get $27$.

$$27+4y=12$$

Subtract $27$ from both sides.

$$4y=12-27$$

Subtract $27$ from $12$ to get $-15$.

$$4y=-15$$

Divide both sides by $4$.

$$y=\frac{-15}{4}$$

Fraction $\frac{-15}{4}$ can be rewritten as $-\frac{15}{4}$ by extracting the negative sign.

$$y=-\frac{15}{4}$$
