Solving Two-Steps Equations (6)

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 the reverse order of how they are applied.

Front

Solve for a: -3a + 8 = 14

Back

a = -2

Front

Solve for w: w + 2 = 8

Back

w = 6

Front

Identify the steps to solve for b in the equation: 5b - 6 = 4

Back

Add 6 to both sides and divide both sides by 5.

Front

Solve for n: 3n + 4 = 7

Back

n = 1

Front

Solve for k: 3k + 5 = 23

Back

k = 6

Front

What is the first step to solve the equation: 2x + 3 = 11?

Back

Subtract 3 from both sides.

Front

What does it mean to perform the inverse operation?

Back

An inverse operation reverses the effect of the original operation (e.g., addition and subtraction are inverses).

Front

Solve for x: 4x - 8 = 0

Back

x = 2
