1) step one is distribute on both sides
2) combine like terms on both sides
3) subtract $19x$ from both sides 
4) last step...

Huh! I'm sorry but this is all new to me I would have to actually see how you did it.
I got it to 20 x so I must be doing something wrong!

anonymous · Answer

$$5(3x-4)+4x=4(5x-2)-12$$1) distribute gives 
$$15x-20+4x=20x-8-12$$

2) combining like terms gives 
$$19x-20=20x-20$$

anonymous · Answer

2) subtract $19x$ 
$$-20=x-20$$ add $20$
$$0=x$$

Thank you. Stupid mistake. I forgot to multiply 5 with 3 x and just put down 3x! It totally changed the problem. Thank you so much!
