Question

alguem tira a minha duvida ? 3/4 . ( x - 1 ) + 1/3 . ( 1 - 2x ) = 2 a resposta é 3 senao for pode me mandar a conta completa obg

Answer 1

Olá!

Vamos aos Calculos...

$\frac{3}{4}*(x-1)+ \frac{1}{3}*(1-2x) =2\\\\ \frac{3x-3}{4}+ \frac{1-2x}{3}=2\\\\ \frac{9x-9}{12}+ \frac{4-8x}{12}=2\\\\ \frac{9x-9+4-8x}{12}=2\\\\ \frac{x-5}{12}=2\\\\x-5=24\\\\x=29$

Bons Estudos!
