<u>Answer:</u>
- The solution of the equation is (-1,-2)
<u>Step-by-step explanation:</u>
- => x - 6y = 11
-6x + 6y = -6
- => 6(x - 6y) = 6(11)
-6x + 6y = -6
- => 6x - 36y = 66
-6x + 6y = -6
- => -30y = 60
- => y = -2
- => x - 6(-2) = 11
- => x + 12 = 11
- => x = -1
Hence, the solution of the equation is (-1,-2)

Using linear functions, we have that:
A.
For Company A:
For Company B:
B. The salaries will be the same after 7 years.
A linear function is given by:
In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the initial value.
Item a:
- For Company A, the salary starts at $31,000, with a raise of $3,000 each year. Thus,
, and the salary after n years is given by:
- For Company B, the salary starts at $38,000, with a raise of $2,000 each year. Thus,
, and the salary after n years is given by:
Item b:
- They will be the same after n years, for which:
Then
The salaries will be the same after 7 years.
