Question

x^2+3x/3=x^2+4x/4urgent

Answer 1

$x^{2} + \frac{3x}{3} = {x}^{2} + \frac{4x}{4} \\ 12 {x}^{2} +12x = 12 {x}^{2} + 12x. \div 12 \\ {x}^{2} + x = {x}^{2} + x \\ {x}^{2} - {x}^{2} = x - x \\ 0 = 0$

Adevarat
Deci oricare ar fi X exista ca solutie a ecuației

Answer 2

X^2+3x/3=x^2+4x/4
x² + x = x² + x
x² - x² + x - x = 0
        0 = 0  (A)   

$oricare\,ar\;fi\;x\,\in\,{R}\;este\;solutie\;pentru\;ecuatia\;data\,!$
