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.

Front

Solve for a: pw = a

Back

a = pw

Front

Solve for w: a = p/w

Back

w = p/a

Front

Solve for p: a = w/p

Back

p = w/a

Front

Solve for y in the equation: y + 2 = 3x

Back

y = 3x - 2

Front

Solve for c in the equation: a = b + c

Back

c = a - b

Front

Solve for y in the equation: 4x + 3y = 9

Back

y = -4/3x + 3

What is the first step to solve the equation 2A = h?

Back

Divide both sides by h to isolate A.

Front

Solve for A in the equation: 2A/h = 2

Back

A = h.
