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

How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform inverse operations in the reverse order of operations used in the equation.

Front

What is the first step to solve the equation 4x + 7 = 23?

Back

Subtract 7 from both sides to get 4x = 16.

Front

What is the second step to solve the equation 4x = 16?

Back

Divide both sides by 4 to find x = 4.

Front

How do you solve the equation 3x + 5 = 4?

Back

Subtract 5 from both sides to get 3x = -1, then divide by 3 to find x = -1/3.

Front

What is the solution to the equation x/3 + 10 = 15?

Back

Subtract 10 from both sides to get x/3 = 5, then multiply by 3 to find x = 15.

Front

How do you solve the equation 9 + 3x = 10?

Back

Subtract 9 from both sides to get 3x = 1, then divide by 3 to find x = 1/3.

Front

What is the solution to the equation 6p - 5 = 13?

Back

Add 5 to both sides to get 6p = 18, then divide by 6 to find p = 3.

Front

What is the importance of checking your solution in a two-step equation?

Back

Checking your solution ensures that the value satisfies the original equation, confirming its correctness.

Front

What are inverse operations?

Back

Inverse operations are pairs of operations that undo each other, such as addition and subtraction or multiplication and division.
