One Step Equations (Adding and Subtracting)

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 x - 15.2 = 76?

Back

Add 15.2 to both sides: x = 76 + 15.2, so x = 91.2.

Front

Write an equation to find how many video games Dominick has if together he and James have 54 games and James has 19.

Back

54 = 19 + x, where x is the number of video games Dominick has.

Front

What is the solution to the equation 2,654 = x + 12?

Back

Subtract 12 from both sides: x = 2,654 - 12, so x = 2,642.

Front

How do you solve the equation 66 = x + 1?

Back

Subtract 1 from both sides: x = 66 - 1, so x = 65.

Front

True or False: In the expression 4x, the number 4 represents multiplication.

Back

True.

Front

What is the first step to solve the equation x + 5 = 10?

Back

Subtract 5 from both sides: x = 10 - 5.

Front

If x - 8 = 12, what is the value of x?

Back

Add 8 to both sides: x = 12 + 8, so x = 20.

Front

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

Back

To isolate a variable means to manipulate the equation so that the variable is on one side by itself.

Front

How do you check if your solution to an equation is correct?

Back

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