The answer is
4.0000000000006667
A because absolute values are always more than or equal to 0
If you would like to solve the system of linear equations, you can do this using the following steps:
2x - y = -1 ... y = 2x + 1
2x + y = -7 ... y = -7 - 2x
The correct result would be: y = 2x + 1, <span>2x + y = -7.</span>
Answer:
The value of 2n - 2 is 4.
Step-by-step explanation:
Given the equation

Subtract 7 from both sides of the equation

Simplify

Now substituting n = 3 in the equation
2n - 2 = 2(3) - 2
= 6 - 2
= 4
Therefore, the value of 2n - 2 is 4.
