Answer:
If x = 3y and 3y = x, then y = 1/3x.
Don’t know if there’s much of an equation for it, but I guess the best way to write it out is 10 + x = -18. Then, you would subtract the 10 from both sides in order to isolate the x. So then you’re left with x = -28. So -28 is your answer.
It’d be 2=-2 ... but then subtract two from both side and the answer is a null set. Also known as “no solution”..
Best of luck in your studies :)
