Two-Step Variable Flashcard

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 the inverse operations in reverse order: first undo addition or subtraction, then undo multiplication or division.

Front

Solve for a: 5(a - 3) = 40

Back

a = 11

Front

What is the first step to solve the equation 8(d - 5) = 72?

Back

First, divide both sides by 8 to simplify the equation.

Front

Solve for d: 8(d - 5) = 72

Back

d = 14

Front

What does it mean to 'distribute' in algebra?

Back

Distributing means to multiply a term by each term inside a parenthesis.

Front

Solve for f: 10(f - 4) = 96

Back

f = 13.6

Front

What is the purpose of checking your solution in an equation?

Back

Checking your solution ensures that the value satisfies the original equation.

Front

Solve for e: 9(e + 3) = 90

Back

e = 7

Front

What is the solution for z in the equation 4z - 8 = 20?

Back
