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 -6w + 1 = -11?

Back

Subtract 1 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation -6w + 1 = -11 after isolating the variable term?

Back

Divide both sides by -6 to solve for w.

Front

Solve for w: -6w + 1 = -11

Back

w = 2

Front

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

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.

Front

Back

Multiply both sides by 3 to eliminate the fraction, then subtract 9 from both sides.

Back

x = 15

Front

What is the first step to solve the equation 9 + 3x = 10?

Back

Subtract 9 from both sides to isolate the term with the variable.

Front

Solve for x: 9 + 3x = 10

Back

x = 1/3

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.
