2|3x-4|=20

-2(x+4)>3x+17

first expand the brackets.

Now do it just the same as any other equation.

BUT REMEMBER

If you multiply OR divide be a negative number then you have to SWAP the sign (< or >) around.

and

I you swap the sides  you also have to SWAP the (< or >) sign around.

Now you try to do it and we can check your working and your answer.   

2|3x - 4| = 20

Divide both sides by 2:

|3x - 4| = 10

Now either  3x - 4 = 10     or 3x - 4 = -10

                        3x = 14              3x = -6

                        x = 14/3   or         x = -2

Thank you so much
