Solve - 3x - 2 = 19.

show each step of work.

-3x-2=19

move - 2 to the other side

sign changes from - 2 to + 2

-3x-2+2=19+2

-3x=19+2

-3x=21

divide both sides - 3 to get + x

-3x/-3=21/-3

Cross out - 3 and - 3, divide by 3 and then becomes - 1*-1*x=x

divide by 3 for 21/-3

21/3=7

-3/3=-1

7*-1=-7

Answer:

x=-7
