Question

$$J = \{ x : x 8 18 \}$$

Solve for x

$x=\frac{Jx_{8}}{18}$
$x_{8}\neq 0$

Steps for Solving Linear Equation

Multiply both sides of the equation by $x_{8}$.

$$Jx_{8}=x\times 18$$

Swap sides so that all variable terms are on the left hand side.

$$x\times 18=Jx_{8}$$

The equation is in standard form.

$$18x=Jx_{8}$$

Divide both sides by $18$.

$$\frac{18x}{18}=\frac{Jx_{8}}{18}$$

Dividing by $18$ undoes the multiplication by $18$.

$$x=\frac{Jx_{8}}{18}$$

Show Solution

Solve for J

$J=\frac{18x}{x_{8}}$
$x_{8}\neq 0$
