Answer 1

A)11x+7=-6

x=7-11-6

X= -10

B)3x+1=19

3x=19-1

3x=18

x=18/3

x=6

C)5+2x=1

2x=1-5

X=-4

X=-4/2

D)5x+3=7

5x=7-3

5x=5

X=5/5 ou 1

E)x-3=1

X=1-3

X=-2

F)2x-3=17

2x=17-3

2x=4

X=4/2

G)-2x-2=-5

-2x=-5+2

-2x=-3

X=-3/-2

H)3x-1=0

3x=0+1

3x=1

X=1/3

I)5-2x=-17

-2x=-17-5

-2x=-22 . -1

2x=22

X=22/2

J)1-x=1

-x=0
