Question

3(n-5)-2(n+8)=11 solve

Answer 1

n= 42

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

Answer 2

n=42

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
