What is the best way to solve a literal equation?

To solve a literal equation means to express one variable with respect to the other variables in the equation.

Step-by-step explanation:

1.

Determine which variable you need to isolate. Isolating a variable means getting the variable on one side of an equation by itself.

2.

Use algebra to solve for the desired variable. Use inverse operations to cancel variables on one side of the equation and move them to the other side. 3.

Keep the equation balanced. Whatever you do to one side of the equation, you must also do to the other side

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
