Let n = the unknown number.
The phrase "five is" tells us to start the equation with "5 ="
"Seven more than" becomes "7 +"
"The product of two and a number" is 2n or (2 * n)
Put it all together and solve:
5 = 7 + 2n
5 = 7 + 2n
5 - 7 = 2n
- 2 = 2n
Divide each side by 2 to isolate the variable
- 1 = n
Your number is - 1
