What does this even mean???42x=7
It means that you need to divide 42 on both sides42x/42=7/420.166.....
It means that something times 42 equals 7. If you have to find the value of x then you would have x=0.16666 repeating or 1/6Divide 42 on both sides42x/42 will cancel out leaving xx=7/42x=0.16666 or 1/6
