Solve Two-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. It typically involves addition or subtraction followed by multiplication or division.

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

Back

To isolate a variable, perform the inverse operations in the reverse order of operations. First, eliminate the constant term by adding or subtracting, then divide or multiply to solve for the variable.

Front

Solve the equation: 0.4x + 13 = 3

Back

x = -25

Front

Solve the equation: -1.5x - 14 = -20

Back

x = 4

Front

What is the first step to solve the equation 2x + 5 = 15?

Back

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

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means ensuring that both sides of the equation are equal by performing the same operation on both sides.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.

Front

What is the inverse operation of multiplication?

Back

The inverse operation of multiplication is division.

Front

If you have the equation x/3 = 5, how do you solve for x?

Back

Multiply both sides by 3 to isolate x, resulting in x = 15.

Front

What is a constant in an equation?

Back

A constant is a fixed value that does not change, such as the numbers in the equation.
