477/36= 13.25
You divide the two numbers to see that 36 will go into 477, 13.25 times.
I think it’s 236.8 correct me if I’m wrong?
3-7 is -4 so it becomes -4x=4 divide both sides by 4 to get -x=-1 a lot of teachers dont like that negative x so you can also divide by -1 again to make it x=1
hope it helps
