Poderiam me ajudar nas seguintes questões:
Equações:
a)x/5-1/4
b)2(x-1)=5x+6
c)5(x+4)=2(x-3)
d)-4(x-1)=2(x-3)
e)3x+2(x-4)=5x-3(x-2)
a) x/5=1/4 b)2(x-1)=5x+6 c)5(x+4)=2(x-3) d)-4(x-1)=2(x-3) e)3x+2(x-4)=5x-3(x-2)
4x/20=5/20 2x-2=5x+6 5x+20=2x-6 -4x+4=2x-6 3x+2x-8=5x-3x+6
4x=5 -3x=8 3x=-26 -6x=-10 5x-8=2x+6
x=5/4 x=-8/3 x=-26/3 x=10/6 3x=14
x=5/3 x=14/3
