what is the value of x in: -x/3 + 4 = 20
Could you guys please tell me how to do it and include the answer. I have other problems like this where x is negative so I just need to know how to do it :) Thanks!
-x/3 = 20-4
-x/3 = 16
multiply by 3
-x = 48
x = -48
Thank you so much!
To find the value of x in the equation -x/3 + 4 = 20, we can follow these steps:
1. Start by isolating the term that contains x. In this case, we can subtract 4 from both sides of the equation:
-x/3 = 20 - 4 (simplifying, we get -x/3 = 16)
2. To get rid of the fraction, multiply both sides of the equation by 3:
3 * (-x/3) = 3 * 16
-x = 48
3. Since we want to find the value of x, we need to isolate x. Multiply both sides of the equation by -1:
(-1) * (-x) = (-1) * 48
x = -48
The value of x in the equation -x/3 + 4 = 20 is x = -48.
If you encounter similar problems where x is negative, you can apply the same steps as mentioned above. Remember to isolate x on one side of the equation by performing the necessary operations in order to find its value.
