Me ajudem♡☆¿

1_ Arme e resolva as equações:
a) 4 (x+3)=1
b) 5 (2x-4)=7(x+1)-3
c)4x-1=3(x-1)
d)3 (x-2)=2x-4
e)2 (x-1)=3x+4x

Answer 1

A= n sei essa


B)
5.(2x-4)= 7(x+1) -3
10x-20= 7x+7-3
10x-7x= 20+7-3
3x =24
x= 24/3
x= 8


C)
4x-1 = 3 (x-1)
4x-1 = 3x-3
4x-3x = 1-3
x = 2


D)
2 (x-1) = 3x+4x
2x-2 = 7x
2x-7x = 2
-5x = 2
x= 2/-5
x= -0,4
