Solve the following math problem and give me an example please C/-7+3.2=2.7

jasenka [17]

C/-7+3.2=2.7

Step 1) Add 7 to both sides because what you do to one side you must do to the other
C/-7+3.2=2.7
 +7 +7
 C/+3.2=9.7

Step 2) Subtract 3.2 from both side
C/+3.2=9.7
 -3.2 -3.2
 C/=6.5

Your answer is C=6.5

If we assume that we have $k$ independent variables and we have $j=1,\dots,j$ individuals, we can define the following formulas of variation:
