n = 42
Step-by-step explanation:
Given expression is: 3 (n-5) - 2 (n+8) = 11
Now, first of all we will multiply the numbers which are outside the brackets to the numbers inside. Which will become:
3n-15 - 2n - 16 = 11
Next the second step is to the change the positions. The numbers that are multiplied by n will be together:
3n - 2n - 15 - 16 = 11
Finally, by solving the above equation. We get:
n - 31 = 11
n = 11 + 31
n = 42
Required answer is n = 42

n=42
Step-by-step explanation:
The first step is to open the brackets by multiplying the vale before the brackets to the values inside the brackets giving attention to the signs which gives:
3n-15-2n-16=11
Then we collect like terms together.
3n-2n-15-16=11
evaluating the above equation we get
n-31=11
n=11+31
=42
