So we'll solve this like this ! First let me tell you as we are changing the places of the values there sign changes too!
So here we go!
$$4x + (-2)=11x+68$$
$$4x-2=11x+68$$
$$4x-11x=2+68$$
$$-7x=70$$ ( now we'll take -7 to the other side)
$$x=-7/70$$(now we'll simply just devide and then we'll get our answer)
$$x=-10$$ $$ANSWER$$
I hope uve understood by now and if not then please be free to ask!
I hope this helps!
