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

What is the first step to solve the equation 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

Solve for x: 2x + 5 = 15

Back

x = 5

Front

Solve for a: 7a - 14 = 42

Back

a = 8

Front

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

Back

Isolating the 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 n: 6n + 4 = -26

Back

n = -5

Front

What is the second step to solve the equation 2s + 1 = 9?

Back

Subtract 1 from both sides, then divide by 2.

Front

Solve for x: 3x - 9 = 0

Back

x = 3

Front

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

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.

Front

Solve for k: 7k - 14 = 42

Back

k = 8
