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.

Front

Solve: 35 = 2.5n

Back

n = 14

Front

What is the first step to solve the equation y + 9.3 = -4.2?

Back

Subtract 9.3 from both sides to isolate y.

Front

Solve: y + 9.3 = -4.2

Back

y = -13.5

Front

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 opposite side.

Front

Solve: -9 = 28 + y

Back

y = -37

Front

What operation would you use to solve the equation -2s = -38?

Back

Divide both sides by -2.

Front

Solve: -2s = -38

Back

s = 19

Front

What is the solution to the equation -11 = n - 6?

Back

n = -5

Front

What is the purpose of checking your solution in an equation?

Back

To verify that the solution satisfies the original equation.
