Question

$$5x9+9=3-1.2$$

Solve for x_9

$x_{9}=-1.44$

Steps for Solving Linear Equation

Subtract $1.2$ from $3$ to get $1.8$.

$$5x_{9}+9=1.8$$

Subtract $9$ from both sides.

$$5x_{9}=1.8-9$$

Subtract $9$ from $1.8$ to get $-7.2$.

$$5x_{9}=-7.2$$

Divide both sides by $5$.

$$x_{9}=\frac{-7.2}{5}$$

Expand $\frac{-7.2}{5}$ by multiplying both numerator and the denominator by $10$.

$$x_{9}=\frac{-72}{50}$$

Reduce the fraction $\frac{-72}{50}$ to lowest terms by extracting and canceling out $2$.

$$x_{9}=-\frac{36}{25}$$
