-3x+20=2

move +20 to the other side

sign changes from +20 to -20

-3x+20-20= 2-20

-3x= 2-20

-3x= -18

divide both sides by -3

to get +x and x by itself

-3x/-3= -18/-3

Answer:

x= 6

-3x + 20 = 2

Subtract 20 to both sides to isolate the x

-3x = 18

And then divide by -3 to both sides since -3 is multiplied to x

x = -6

To check you work plug back into the equation

-3(-6) + 20 = 2

-18 + 20 = 2

2 = 2

Which means that it is the right answer
