2 + m < 2 is m < 0 but how would I check it?

Answer 1

you would try to get the variable alone on one side. to do this you would subtract 2 from both sides. this would completely cancel out the 2 in 2+m leaving the variable alone and you would get m<0

Answer 2

subtract 2 from each side

2-2+m<2-2
m<0
