i) 2(x - 1) = 3x + 4


k) 3(5 - x) - 3(1 - 2x) = 42


1) (x + 10) - 2(x - 5) = 0


m) 3(2x + 3) - 4(x - 1) = 3


n) 7(x - 1) - 2(x - 5) =x-


o) 2(3 - x) = 3(x - 4) + 15


j) 3(x - 1) - 7 = 1!


1. Resolva as equações:


a) 3x - 7 = 2x + 5


b) 7x + 8 = 4x - 10


C) 4x - 15 =-2x+ 3


d) 2x - 4 - 8 = 4x


e) 3x = x + 1 + 7


f) 360 + 36x = 30


g) 4x - 1 =3(x-1 )


h) 3(x - 2) = 2x - 4
