Front

What is the principle of balancing equations?

Back

The principle of balancing equations states that whatever you do to one side of the equation, you must do to the other side to maintain equality.

Front

How do you isolate a variable in an equation?

Back

Front

How do you solve the equation y - 33 = 147?

Back

Add 33 to both sides: y = 147 + 33, so y = 180.

Front

How do you solve the equation x - 2 = 12?

Back

Add 2 to both sides: x = 12 + 2, so x = 14.

Front

How do you solve the equation 17 = x + 3?

Back

Subtract 3 from both sides: x = 17 - 3, so x = 14.

Front

How do you solve the equation 16 = n + 6?

Back

Subtract 6 from both sides: n = 16 - 6, so n = 10.
