Question

a=3 , b=11 => calculati 7a-2b/2a+3b rapid va rog dau coroana la cel mai bun raspuns :]

Answer 1

$a = 3$

$b = 11$

$\frac{7a - 2b}{2a + 3b} = \frac{7 \times 3 - 2 \times 11}{2 \times 3 + 3 \times 11} = \frac{21 - 22}{6 + 33} = \frac{ - 1}{39} = - \frac{1}{39}$

Answer 2

$21 - \frac{22}{3} + 33$
$= 54 - \frac{22}{3}$
$= \frac{140}{3}$
