Question

Ajutor va rog
1. Rezolvați in R ecuatiile:
$a) \: 3(2x - 1) - 5(3x - 1) = 1$
b) 3(y+4)-(-3+y)*(-2)=3
c) 4(t+3)-5(1-2t)=6t-1
2. Rezolvați in R ecuatiile:
$\frac{1}{2}(x - \frac{1}{3}) - \frac{1}{3} (x - \frac{1}{2} ) = x + \frac{1}{6}$
3. Rezolvați in R ecuatiile:
$a) \: (x - 1)(x + 1) - {x}^{2} = x - 1$
$b) \: (y + 1)(y + 2) + 2y + 1 = y2 + 4y$
si din poza 12 a, b si 13 a, b
