This question is basically asking what is -60 plus 25. It said that -60 is less than its previous altitude which means that we need to add to get the previous altitude. When you add a negative to a positive number all you do is count backwards just like you were subtracting. -60 + 25 equals -35. We can check this by subtracting 25 and -35 to get -60.
The submarine previous altitude is -35. <span />
-6x + y = - 4 / + 6x ;
y = 6x - 4 ;
We substitute y in first equation : -5x + 3( 6x - 4 ) = 12;
-5x + 18x - 12 = 12 ;
13x - 12 = 12 ;
13x = 24 ;
x = 24 / 13 ;
y = 6*(24 / 13 ) - 4 ;
y = 144 / 13 - 4 ;
y = 144 / 13 - 52 / 13;
y = 92 / 13 ;
The solution is x = 24 / 13 and y = 92 / 13 ;
