How do you isolate a variable in a literal equation?

Back

To isolate a variable, you perform inverse operations to both sides of the equation until the variable is alone on one side.

Solve for h: V = πr²h

Back

h = V/(πr²)

Solve for x: ax + c = R

Back

x = (R - c) / a

Solve for F: S = 3F - 24

Back

F = (S + 24)/3

Front

Solve for R: IR = V

Back

R = V/I

What is the first step in solving a literal equation?

Back

Identify the variable you want to isolate and determine the operations affecting it.

If you have the equation x = by + v, how do you solve for y?

Back

y = (x - v)/b

What does it mean to rearrange an equation?

Back

Rearranging an equation means changing the order of the terms or isolating a different variable.

Solve for y: 2x + 3y = 12

Back

y = (12 - 2x)/3
