2x – 3 = 5 2x = 5 + 3 x = 8 / 2 x = 4

3x – 1 = x + 9 3x – x = 9 + 1 2x = 10 x = 10 / 2 x = 5

5 – x = 2 5 – 2 = x 3 = x

$$\frac {3x-1}{5}$$ = 4 3x – 1 = 4 * 5 3x = 20 + 1 x = 21 / 3 x = 7

$$\frac {3x}{2}$$ + 4 = 7 3x + 4*2 = 7*2 . . . . . .$$\frac {3x}{2}$$ = 7 – 4 3x = 14 — 8 . . . . . . . . 3x = 3 * 2 x = 6 / 3 . . . . . . . . . . . 3x = 6 x = 2 . . . . . . . . . . . . . . x = 6 / 3 = 2

$$\frac {2x–1}{3}$$ +$$\frac {x}{2}$$ = 9 2· (2x–1) + 3 · x = 9 · 6 4x – 2 + 3x = 54 7x = 54 + 2 x = 56 / 7 = 8
