Type your math problem... 3 -2n = 81

x

Question

Solve the equation

n = - 39

Evaluate

3 - 2 n = 81

Move the constant to the right-hand side and change its sign

- 2 n = 81 - 3

Subtract the numbers

- 2 n = 78

Change the signs on both sides of the equation

2 n = - 78

Divide both sides

\frac{2 n}{2} = \frac{- 78}{2}

Divide the numbers

n = \frac{- 78}{2}

Solution

More Steps

Evaluate

\frac{- 78}{2}

Reduce the numbers

\frac{- 39}{1}

Calculate

- 39

n = - 39
