42-x=58
or, -x=58-42
with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.
or, -x= 16
or,x=-16.
therefore x=-16...

Draw a straight line. Label the left side "0" and then make lines with
"2" "3" and "4".
1/3 means it i 1/3rd of 1. Which means you need to divide everything from 0 - 1 into 2 segments. The first segment on the left side is your 1/3rd spot. The next one is your 2/3rd place, and then finally the 1 is your 3/3 (or one whole.)
The minimum and maximum of the set alone is 25 and 60. The range of that 35. So, the number is not less than or more than 25 or 60.
The set in order:
25, 36, 48, 52, 60
The median is 48, so the number has to be less than 48. Let's see if the number may be less than 36.
36+48
84
42
So, the number is right between 36 and 48.
43.5×2
87
Let's subtract 48 from that
87-48
39
So, the mssing value is 39. Let's check.
25, 36, 39, 48, 52, 60
48+39
87÷2
43.5
So the missing value is 39.
