The last name I am pretty sure of it.
-7x+12-2x=23+13x
First take away 13x from the right side and put it on the left side adding taking it away from -7x
-7x(-13x)=-20x
-20x+12-2x=23
then add 2x to -20x
and move 12 to the other side, minus it off of 23
-18x=11
then divide -18x on both sides
then x=-11/18
This is a VERY long question XD
360 divided by 115 = 3.13. Then you divide the 103 by the 3.13 = 32.90
