Question

Solve -3x - 2 = 19.
show each step of work.

Answer 1

-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
