Solving 2 step Equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

What is the first step to solve the equation 3c + 5 = 23?

Back

Subtract 5 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation 3c + 5 = 23 after subtracting 5?

Back

Divide both sides by 3 to solve for c.

Front

How do you write an equation for a word problem involving students on buses?

Back

Identify the total number of students and express the relationship using variables, e.g., 331 = 6x + 7.

Front

What does the variable represent in the equation 331 = 6x + 7?

Back

The variable x represents the number of students in each bus.

Front

How do you isolate the variable in the equation 15 = 2a + 7?

Back

Subtract 7 from both sides and then divide by 2.

Front

What is the solution to the equation -3x + 5 = -16?

Back

x = 7.

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations help to isolate the variable by undoing the operations applied to it.

Front

What is an example of a two-step equation?

Back

An example is 2x + 3 = 11.

Front

How do you check your solution for an equation?

Back

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