Game System C Last month, you sold 21 systems. The total for the last two months is 37. Write and solve an equation to find how many systems you sold this month. Let c = number of systems sold this month Equation: Systems Sold:

Sagot :

You sold 21 systems last month.

The total systems sold in the last two months is 37 (that means this month and last month)

How many systems have you sold this month?

Let c = number of systems sold this month

Then we may write the following equation

[tex]c+21=37[/tex]

Where c represents the number of systems sold this month

21 represents the number of systems sold last month

Then the sum of these two months must be equal to 37 (total systems sold in two months)

Now let us solve the equation for c

[tex]\begin{gathered} c+21=37 \\ c=37-21 \\ c=16 \end{gathered}[/tex]

Therefore, you have sold 16 systems this month
