wtf?

add 8 to both sides, then multiply both sides by 4.
j<48

j/4  8 < 4
first bring the 8 over to the right hand side
j/4 < 4+8
j/4 < 12
multiply both sides by 4
j < 12*4
j < 48
d is the answer

an inequality is like a normal equation but the answer has a range rather than one specific answer. So you need to get J by itself. Add 8 to 4=12 so j/4=12........ now divide multiply 12 by 4. j<48

J= any number from 47 or less...anything over 47 is wrong answer. For example:
J/48<4
J= 48 then take 48 divided by 4 and subtract 8 that would equals to 4 which is not less than 4 so its wrong answer. but if u substitute J with lesser # than 48 you will come up with the right answer. Do you follow me?

an inequality is type of a classic equation notwithstanding the answer has a form truly than one certain answer. so that you want to get J by using itself. upload 8 to 4=12 so j/4=12........ now divide multiply 12 by using 4. j<40 8

Here is how,
J / 4  8 < 4 Treat "< " like " = " (equal sign)
Therefore,
J / 4 < 4 + 8
J / 4 < 12
J < 12 x 4
J < 48

D
8+4=12
j/4<12
times each side by 4
j<48
