First Subtract the lowest variable which would be "y" from 9y. 9y changes to 8y and y cancels out, bring everything else down. the equation is now 8y-1=-25. Now add positive one to both sides -25 becomes -24 and -1 cancels out. the equation is now 8y=-24. -24 divided by 8 equals -3 and the 8y cancels out. the equation is now x equals -3.
