Solve 7/3 - (3x+4)/21 =5

Evaluate

\frac{7}{3} - \frac{3 x + 4}{21} = 5

Multiply both sides of the equation by LCD

(\frac{7}{3} - \frac{3 x + 4}{21}) \times 21 = 5 \times 21

Simplify the equation

More Steps

45 - 3 x = 5 \times 21

Simplify the equation

45 - 3 x = 105

Move the constant to the right side

- 3 x = 105 - 45

Subtract the numbers

- 3 x = 60

Change the signs on both sides of the equation

3 x = - 60

Divide both sides

\frac{3 x}{3} = \frac{- 60}{3}

Divide the numbers

x = \frac{- 60}{3}

Solution
