The answer to the question is C
Answer:
x
=
21/2
Step-by-step explanation:
Move all terms not containing x to the right side of the equation.
3x=x+21
Move all terms containing x to the left side of the equation.
2x=21
Divide each term by
2
and simplify.
x
=
21/2
The solution for the given equation is a = -5.

What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
To find the solution to the given equation:
Negative (5 minus (a + 1)) = 9 minus (5 minus (2a minus 3)) can be expressed mathematically as follows.
- - (5 - (a + 1)) = 9 - (5 - (2a - 3))
Using the principle of PEMDAS, all the parenthesis values are first solved.
- - (5 - a - 1) = 9 - (5 - 2a + 3)
- -5 + a + 1 = 9 - 5 + 2a - 3
Collect like terms:
- -5 + 1 - 9 + 5 + 3 = 2a - a
- -5 = a
That is a = -5.
Therefore, the solution for the given equation is a = -5.

The correct question is given below:
What is the solution to the equation Negative (5 minus (a + 1)) = 9 minus (5 minus (2a minus 3))? a = –5 a = –3 a = 3 a = 5
Answer:
11≤√134≤12
Step-by-step explanation:
11^2 is 121
and 12^2 is 144
so √134 would have to fall between these numbers
