Question

Rezolvati ecuatia: x-1/5+ x+1/3=2

Answer 1

$\frac{x-1}{5} + \frac{x+1}{3} = 2$  Aducem la fiecare numitorul 15 si o sa scapam de el

[tex]3(x-1) +5(x+1)= 30 \\ \\ 3x-3 +5x+5 = 30 \\ \\ 8x = 30-5 +3 \\ \\ 8x = 28\\ \\ x = 28 /8 [/tex]

Answer 2

x - 1/5 + x + 1/3 = 2 
15 x - 3 + 15 x + 5 = 2 × 15 
30 x = 30 - 2 
x = 28 /30 = 14/15 



( x - 1) / 5 + ( x + 1)/3 = 2 
3 ( x - 1) + 5 ( x + 1) = 2×15 
3 x - 3 + 5 x+ 5 = 30 
8 x = 30 - 2
x = 28/8 = 7/2 = 3,5
