t + 4 t - 3 = 3 (3 t - 9)

Add similar elements:

t + 4 t = 5 t

5 t - 3 = 3 (3 t - 9)

Expand

3 (3 t - 9) : 9 t - 27

5 t - 3 = 9 t - 27

Move

3

to the right side

5 t = 9 t - 24

Move

9 t

to the left side

- 4 t = - 24

Divide both sides by

- 4

t = 6

\frac{z}{2 - i} = - 1 + 2 i

\frac{x}{4} = \frac{2}{3}

\frac{2}{3} (6 x + 6) = 4 x + 4

\frac{5}{- 3 + 3} + \frac{2}{- 3 ^{2} - 9} = \frac{4}{- 3 - 3}

\frac{9 - x}{2} = 13
