Question

a) 3-2(×+3)=×-18
b)3(×-4)=-1(3×-1)
c)5(×/5-1)=×-6(2×/3+4)
Preciso saber a conta !! Me Ajudem !!

Answer 1

a) 3-2x-6=x-18
2x-x=-18+6-3
x= -15

b) 3x-12 = -3x+1
3x+3x=1+12
6x=13
x=13/6

c)5x/5 -5 = x-12x/3 -24
(simplifica o 5) x-5 = x- (simplifica o 12 com 3) 4x - 24
x-x+4x=-24+5
4x=-19
x=-19/4
