C)4(3×+1)=6×+1+3(×+3)

D)7×-6=×-1

ME AJUDEM POR FAVOR É PRA HJ.​

Answer 1

A)

3x-2x=6

1x=6

x=6/1

x=6

B)

15x-2(3x-9)=59

15x-6x+18=59

15x-6x=59-18

9x=41

x=41/9

x=4,5

C)

4(3x+1)=6x+1+3(x+3)

12x+4=6x+1+3x+9

12x-6x-3x=-4+1+9

6x=6

x=6/6

x=1

D)

7x-6=x-1

7x-x=-1+6

6x=5

x=5/6

x=0,83
