Como despejar "x" 7x/2+1/2=-2/3-x?
[tex]mcm=6 \\ 3(7x)+3(1)=2(-2) \\ 21x+3=-4 \\ 21x=-3-4 \\ 21x=-7 \\ x=\frac{-7}{21} \\ \\ x=\frac{-1}{3}[/tex]
ResoLvemos :
(7x/2) +(1/2) = (-2/3) -x
MCM de (2 y 2) = 2
(7x+1)/2 = (-2-3x)/3
Multiplicamos en "Aspa" :
3*(7x+1) = 2*(-2-3x)
21x+3 = -4-6x
21x+6x = -4-3
27x = -7
x = -7/27
