You can put this solution on YOUR website! 4x-y<3
step 1 - subtract 4x to get
-y<-4x+3
step 2 - divide by -1 ; don't for get the negative rule about switching the inequality when multiply or divide by - number. We get
y >4x - 3

and 3x+4y<12
step 1 - subtract 3x to get
4y<-3x + 12
step 2 - divide by 4 to get
y < (-3/4)x + 3
here is the graph
