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.

Front

Solve for x: 2x + 3x + 4 = 44

Back

x = 8

Front

What is the first step to solve the equation 7 + a/3 = 5?

Back

Subtract 7 from both sides to isolate the term with a.

Front

Solve for a: 7 + a/3 = 5

Back

a = -6

Front

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

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.

Front

Solve for a: 20 = 2 - a

Back

a = -18

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside a set of parentheses.

Front

Solve for b: -11 + 3(b + 5) = 7

Back

b = 1

Front

What is the purpose of combining like terms in an equation?

Back

Combining like terms simplifies the equation, making it easier to solve.

Front

Solve for c: 3c + 5 = 23

Back

c = 6
