The equation appears to be made already.
Using the Order of Operations, consider what operations are being done to the variable "c". They are
• divide c by 4
• add -5 to the quotient.
To find the value of "c", we "undo" these operations in reverse order. To undo the addition of a number, we add the opposite of the number. So, we will first
• add 5 to the equation
This gives
Now, the next operation that we need to undo is the division by 4. We can undo that by multiplying the equation by 4. So, we will next
• multiply the equation by 4
This gives
The solution is c = 36.
