Question

2x+3 supra 4 +5x =x-1 supra 2 - 3
​

Answer 1

Răspuns:

$2x + \frac{3}{4} + 5 = x - \frac{1}{2} - 3 \\ 2x - x = - \frac{1}{2} - 3 - \frac{3}{4} - 5 \\ x ^{4} = - \frac{1}{2} ^{2} - 3 ^{4} - \frac{3}{4} - 5 ^{4} \\ \frac{4x}{4} = - \frac{2}{4} - \frac{12}{4} - \frac{3}{4} - \frac{20}{4} | \div 4 \\ 4x = - 2 - 12 - 3 - 20 \\ 4x = - 37 \\ x = - \frac{37}{4}$

acesta este răspunsul
