The product of 25 and an unknown number is subtracted from 36. the result is -114.
what is the value of the unknown number?

25•x=25x. 36 - 25x = -114. ( 36 + -25x = -114 )
- 36. -36
- 25x = -150
÷ - 25. ÷ - 25
X = 6
To find the answer to this equation, you try to get the variable X. By its self. In order to get X by itself, you simply do the opposite of what's being done. The first thing you should do is subtract 36 from both sides. The reason why I added is because when adding or subtracting negatives, add the opposite. Since it was -114 - 36, you would change it to -114 + -36. Which equals -150. Next you would divide -25 from both sides. The reason why you would divide -25 to from both sides is because, you are trying to isolate the variable X. The answer you would get is 6. To check if the answer you have got is correct, plug 6 in for the variable X. This is how it would look: 36 - 25(7.2) = -114
You would use parentheses for multiplication. Next you would multiply 25 and 7.2 the answer you should get should be, 150. So far the equation should look like this: 36 - 150= -114. Then you would subtract 36 from both sides. Your final answer should look like this:
-150 = -150. So the answer to the question would be 6.
