Answer: OPTION D
Step-by-step explanation:
You need to remember this property:
And remember that:
Then, the first step is rewrite the expression:
Now, to find the corresponding equivalent expression, you need to simplify the expression.
Therefore, the equivalent expression is the following:
Finally, you can observe that this matches with the option D.
Answer:
132
Step-by-step explanation:
(n - 4) - 3 = 3 - (2n + 3)
Let's first start by removing the parenthesis.
(n-4) = +(n-4) so we just remove the parenthesis without changing the signs. So the first part of the equation will be n - 4 - 3.
Before (2n+3), we can notice a minus sign (-) which means that to remove the parenthesis, we need to change the signs of the numbers and variables inside.
-(2n+3) = -2n-3
So the second part of the equation becomes 3 -2n - 3
(n-4) - 3 = 3 - (2n+3)
n - 4 - 3 = 3 - 2n - 3
n - 7 = -2n
Now we need to put the variables apart and the constants apart. So we subtract n from each side:
n - n - 7 = -2n - n
-7 = -3n
Divide both sides by -3
(-7)/(-3) = (-3n)/-3
7/3 = n
In the equation (n-4) - 3 = 3-(2n+3), the value of n is n=7/3
Hope this helps! :)
