First, identify the common terms. The terms 6y and -7y are like terms because they have the same variable expression 'y' attached to them. So we can say 6y-7y=y%286-7%29=y%28-1%29=-1%2Ay=-y (basically factor out the GCF 'y' and subtract then simplify). In short, 6y-7y=-y


In the bigger picture, this means: -3%2B6y%2B4x-7y=-3%2B%286y-7y%29%2B4x=-3-y%2B4x=4x-y-3


So -3%2B6y%2B4x-7y=4x-y-3
