Distribute first... 5(1)=5 5(4m)=20m So for the left side it's 5+20m Now u have to do the same thing for the right side 2(3)=6 2(10m)=20m So for the right side it's 6+20m Now that u have solved both sides u have to isolate the m 5+20m=6+20m -5 -5 ---------------------- 20m=1+20m -20m -20m ------------------------ 0=1 Therefore there is no solution
