81 - \frac{4 x}{7} = 21

x = 105

Solution steps

81 - \frac{4 x}{7} = 21

Move

81

to the right side

- \frac{4 x}{7} = - 60

Multiply both sides by

7

- 4 x = - 420

Divide both sides by

- 4

x = 105

\frac{m}{4} = \frac{3}{5}

y = ∣ - 3 ∣ - 5

- 9 + \frac{y}{- 3} = - 6

- 4 = \frac{2}{3} b

5 x - (x - 6) = 2
