If we let the number be represented by the variable x , then we can show the "product of a number and -4" as:
-4x
Then to show "9 less than " this product, we can write:
-4x - 9
Lastly, the words "is 35" means equal to 35 or = 35
T
So we can write the final equation as:
-4x - 9 = 35
You can solve this equation using inverse operations:
First add 9 to both sides of the equation:
-4x -9 + 9 = 35 + 9
The result is -4x = 44
Divide both sides of the equation by -4:
-4x / (-4) = 44/(-4)
The result is x= -11
You can verify your solution:
The product of -11 and -4 is 44. Then 9 less than 44 is 44 - 9 or 35.
