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.

Front

What is the first step in solving the equation 5x - 8 = 32?

Back

Add 8 to both sides.

Front

What do you do after adding 8 to both sides of the equation 5x - 8 = 32?

Back

Divide both sides by 5.

Front

Solve for x: 5x + 7 = 12.

Back

x = 1.

Front

What is the solution to the equation 3c + 5 = 23?

Back

c = 6.

Front

How do you isolate the variable in the equation 7 + a/3 = 5?

Back

Subtract 7 from both sides and then multiply by 3.

Front

What is the solution for a in the equation 7 + a/3 = 5?

Back

a = -6.

Front

Solve for y: -2y = 20.

Back

y = -10.

Front

What is the purpose of performing the same operation on both sides of an equation?

Back

To maintain the equality of the equation.

Front

What does it mean to isolate a variable?

Back

To manipulate the equation so that the variable is on one side and all other terms are on the other side.
