Question

Solve the equation

v = 21

Evaluate

4 v = 8 v - 84

Move the variable to the left side

4 v - 8 v = - 84

Subtract the terms

More Steps

Evaluate

4 v - 8 v

Collect like terms by calculating the sum or difference of their coefficients

(4 - 8) v

Subtract the numbers

- 4 v

- 4 v = - 84

Change the signs on both sides of the equation

4 v = 84

Divide both sides

\frac{4 v}{4} = \frac{84}{4}

Divide the numbers

v = \frac{84}{4}

Solution

More Steps

Evaluate

\frac{84}{4}

Reduce the numbers
