Solving One-Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step by performing the same operation on both sides of the equation.

Back

Multiply both sides by 3: p = -6 * 3 = -18.

Back

Divide both sides by -11: b = -44 / -11 = 4.

Back

Subtract 19 from both sides: k = 10 - 19 = -9.

Front

Back

Add 19 to both sides: a = -30 + 19 = -11.

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the other side.

Back

Subtract 5 from both sides: x = 12 - 5 = 7.

Front

Back

Divide both sides by 3: y = 12 / 3 = 4.
