Question

cine ma poate ajuta cu ex. 9
Va rog frumos!
Multumesc!

Answer 1

$3 \frac{3}{5} x + 1 = 2x + \frac{9}{4} \\ \frac{15 + 3}{5} x + 1 = 2x + \frac{9}{4 } \\ \frac{18x}{5} + 1 = 2x + \frac{9}{4}$
aduci la acelaşi numitor :

$72x + 20 = 40x + 45 \\ 72x - 40x = 45 - 20 \\ 32x = 25 \\ x = \frac{25}{32}$
