Question

Aflati ,,floricica" din egalitatea:


[ ( 9xf-21) :3+75 ] :7=358-74x4​

Answer 1

$((9x - 21) \div 3 + 75) \div 7 = 358 - 74 \times 4$

$(27x - 63 + 75) \div 7 = 358 - 296$

$(27x + 12) \div 7 = 62$

$\frac{27x + 12}{7} = 62$

$27x + 12 = 434$

$27x = 434 - 12$

$27x = 422$

$x= \frac{422}{27}$
