δ) 2(x-4)-3=500-2 г) 4/2x+3)-3=5x-2(x+3)

б) $$2(x - 4) - 3 = 5x - 2$$ $$2x - 8 - 3 = 5x - 2$$ $$2x - 11 = 5x - 2$$ $$2x - 5x = 11 - 2$$ $$-3x = 9$$ $$x = \frac{9}{-3}$$ $$x = -3$$

г) $$4(2x + 3) - 3 = 5x - 2(x + 3)$$ $$8x + 12 - 3 = 5x - 2x - 6$$ $$8x + 9 = 3x - 6$$ $$8x - 3x = -6 - 9$$ $$5x = -15$$ $$x = \frac{-15}{5}$$ $$x = -3$$
