HELP ME!!!

Answer 1

Oie, td bom?

$a) \\x^2 + x^2 - 2x^2 =\\2x^2 - 2x^2 = 0\\\\b) \\8x + \frac{1}{2} x= \frac{17}{2} x\\\\c)\\3a - \frac{2}{3}a = \frac{7a}{3}\\\\d) \frac{1}{2}x - \frac{1}{3}x = \frac{5}{6} x\\\\e) 2x + \frac{1}{3}x- \frac{3}{4} x =\\\frac{7}{3}x -\frac{3}{4}x =\\\\\frac{19}{12}x$

Espero ter ajudado...tchau e bons estudos!!
