The point of "solving an equation" is to get "y= something" which means you want to get rid of all the numbers on the left. 6(4)= 24 so this is really -2/y+ 24= 6. That "24" is added so we can get rid of it by doing the opposite: subtract 24 from both sides of the equation: -2/y+ 24-24= 6- 24 or -2/y= -18. The "2" is multiplied and the opposite of multiplying is dividing: (-2/y)/-2= -18/(-2) or 1/y= -9. Now invert: reverse each fraction: y= -1/9.
