Question

1)resolva as equaçoes abaixo:

a)2(x-3)=-3(x-3)

b)4(5x-3)-64(3-x)-3(12x-4)=96

c)5(x+1)+6(x+2)=9(x+3)

me ajuden pfv

Answer 1

a) 2x-6=-3x+9
2x+3x=9+6
5x=15
x=15/5
x=3


b) 4(5x-3)-64(3-x)-3(12x-4)=96
20x-12-192+64x-36+12=96
20x+64x=-12-193-36+12-96
84x=-325
x=-325/84


c) 5(x+1)+6(x+2)=9(x+3)
5x+5+6x+12=9x+26
5x+6x-9x=26-5-12
11x-9x=9
2x=9
x=9/2
