_____ - ______ = _________

3 10 10

-1/2
Me ajudem por favor

Answer 1

Resposta:

Explicação passo a passo:

"2(x+2)/3-4(1-x)/10 = 3.(1+x)/10-1/2"

[10.2(x+2)-3.4(1-x)]/30=[3.(1+x)-5]/10"

[20(x+2)-12.(1-x)]/30=[3+3x-5]/10"

(20x+40-12+12x)=30(3x-2)/10"

32x+28=3.(3x-2)"

"32x+28 = 9x-6"

32x-9x = -6-28"

"23x= -34"

"x = -34/23"
