How do you isolate a variable in a literal equation?

Back

To isolate a variable, you perform inverse operations to move other terms to the opposite side of the equation.

Solve for y: 5x - y = 16

Back

y = 5x - 16

Front

Solve for y: 4x + 3y = 9

Back

y = -4/3x + 3

Front

Solve for y: 8x + 4y = 16

Back

y = -2x + 4

Front

Solve for y: 3x + y = 12

Back

y = -3x + 12

What is the first step in solving the equation pV = nRT for R?

Back

Divide both sides by nT to isolate R.

Front

Solve for R: pV = nRT

Back

R = pV/nT

What does it mean to rearrange an equation?

Back

Rearranging an equation means changing the equation's form to solve for a different variable.

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
