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: 4x + 7 = 23

Back

x = 4

Front

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

Back

Subtract 11 from both sides.

Front

Solve for x: 8x - 6x + 4 + 5 = 19

Back

x = 5

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 other side.

Front

Solve for a: 7 + a/3 = 5

Back

a = -6

Front

What is the purpose of balancing an equation?

Back

The purpose of balancing an equation is to maintain equality by performing the same operation on both sides.

Front

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

Back

b = 1

Front

What is the second step in solving the equation: 2x + 3 = 11?

Back

Subtract 3 from both sides.

Front

Define 'variable' in the context of algebra.

Back

A variable is a symbol, often represented by a letter, that stands for an unknown value.
