The equation
(y + 5) + y = 6
shows the substitution method being used to solve the system of linear equations. So the correct option among all the options given in the question is option "D".
For a better explanation, let us first write down the two equations given in the question.
x + 5 = 6
and
x = y + 5
Now the thing that has been done is that the value of x in the first equation has been replaced by the value of x that is given in the second equation. this is actually the substitution method of solving equations.
Answer:
55 percent of the surveyed employees preferred to eat lunch at their desk.
Step-by-step explanation:
Here, the total number of surveyed employees = 40

Answer:
-29
Step-by-step explanation:
y = 7-36
y = -29
In expanded form that would be 4 + 0.2 + 0.09 + 0.003
Hope that helps :)
