Question

Rezolva ecuatiile
A)2X-0,3=0,5X+1
B)2radical 3x+2=radical12X+2

Answer 1

Răspuns:

$a)2x - 0.3 = 0.5x \times + 1 \\ 2x - 0.5x = 1 + 0.3 \\ 1.5x = 1.3 \\ \frac{15}{10} x = \frac{13}{10} \\ x = \frac{13}{10} \div \frac{15}{10} \\ x = \frac{13}{10} \times \frac{10}{15} \\ x = \frac{13}{15}$
