Solving 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.

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 t: -4 = 2t - 2

Back

t = -1

Front

Solve for m: -5 = 3m - 14

Back

m = 3

Front

Solve for d: 5d - 6 = 9

Back

d = 3

Front

Solve for z: 0 = 8z + 8

Back

z = -1

Front

Solve for v: 8 = 4v + 12

Back

v = -1

Front

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

Back

Subtract 3 from both sides to get 2x = 8.

Front

What is the second step to solve the equation 2x = 8?

Back

Divide both sides by 2 to get x = 4.

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means keeping both sides equal by performing the same operation on both sides.
