Basic 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

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 x: -4 + 4x = 36

Back

x = 10

Front

What is the first step to solve the equation 33 = 4a - 7?

Back

Add 7 to both sides to isolate the term with a.

Front

Solve for a: 33 = 4a - 7

Back

a = 10

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means performing the same operation on both sides to maintain equality.

Front

Solve for x: 11x - 8 = 3

Back

x = 1

Front

What is the solution to the equation -10z = 40?

Back

z = -4

Front

Back

Add 10 to both sides, then multiply by 5 to isolate x.
