Solve for w: 11 = 6w - 1

Back

w = 2

Front

Solve for x: 2x - 3 = 1

Back

x = 2

Front

Solve for x: 4x + 7 = 23

Back

x = 4

Front

What is the first step to solve the equation 3x + 5 = 20?

Back

Subtract 5 from both sides to get 3x = 15.

Front

What is the second step to solve the equation 3x = 15?

Back

Divide both sides by 3 to get x = 5.

Front

What does it mean to 'balance' an equation?

Back

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