How do you isolate a variable in a literal equation?

Back

To isolate a variable, you can use inverse operations such as addition, subtraction, multiplication, or division to rearrange the equation.

Front

Solve for a: pw = a

Back

a = pw

Front

Solve for a: a = w/p

Back

a = w/p

Solve for y in the equation: 2x + 3y = 4

Back

y = (4 - 2x)/3

Front

What is the first step to solve for t in the equation: s = 2t + f?

Back

Subtract f from each side.

Solve for F in the equation: S = 3F - 24

Back

F = (S + 24)/3

Front

Solve for x: x = by - v

Back

x = by + v

Front

What does it mean to rearrange an equation?

Back

Rearranging an equation means to change the order of the terms or to isolate a specific variable.
