One-step Equations (addition/subtraction)

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step, typically involving addition or subtraction to isolate the variable.

Front

How do you solve the equation S + 18 = 24?

Back

Subtract 18 from both sides: S = 24 - 18, so S = 6.

Front

What is the solution to the equation g - 15 = 30?

Back

Add 15 to both sides: g = 30 + 15, so g = 45.

Front

Which equation represents the situation: Jack had some markers and then bought 6 more. Now he has a total of 10 markers?

Back

m + 6 = 10.

Front

How do you isolate the variable in the equation x + 7 = 12?

Back

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

Front

What is the solution to the equation y - 33 = 147?

Back

Add 33 to both sides: y = 147 + 33, so y = 180.

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 by itself, making it easier to solve.

Front

What is the first step to solve the equation x - 4 = 10?

Back

Add 4 to both sides: x = 10 + 4, so x = 14.

Front

How do you check the solution of an equation?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What is the solution to the equation 5 + z = 12?

Back

Subtract 5 from both sides: z = 12 - 5, so z = 7.
