Answer:
A. x-2y-3z = 1/2
Step-by-step explanation:
yess.. if you take solve every equation then you will get same equation from all the equations
-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
