-9=-2/3 s

- 9 = - \frac{2}{3} s

s = \frac{27}{2}

Solution steps

- 9 = - \frac{2}{3} s

Switch sides

- \frac{2}{3} s = - 9

Multiply both sides by

3

- 2 s = - 27

Divide both sides by

- 2

s = \frac{27}{2}

\frac{x}{4} = \frac{5}{7}

x, x + y - 2 z = 5

14 - (x + 1) = 2 x - 2

- 5 x + 1 = 31

6 + u = - 3
