Question

Resolva as seguintes equações
d) x/2 + x/3 =1
E) x/2+4=1/3
F) x/2+3/4=1/6
Se poderem me ajuda eu agradeço muitoooo

Answer 1

Resposta:

Explicação passo-a-passo:

d)

$\frac{x}{2} +\frac{x}{3} =1\\\frac{3x+2x}{6} =1\\5x=6\\x=\frac{6}{5}$

$\frac{x}{2} +4=\frac{1}{3} \\\frac{x+8}{2} =\frac{1}{3} \\3(x+8)=2\\3x+24=2\\3x=2-24\\3x=-22\\x= \frac{-22}{3}$

$\frac{x}{2} +\frac{3}{4} =\frac{1}{6} \\\frac{2x+3}{4} =\frac{1}{6} \\6.(2x+3) =4\\12x+18=4\\12x=4-18\\x=\frac{-14}{12}$
