Set up equation
Step 1: Simplify

Step 2:Multiply by conjugate

Step 3:Simplify

We can reduce this and we must make the imaginary number and real number serpate equations.

Reduce each by 2

Answer:
(x, y) = (1, 3)
Step-by-step explanation:
given the 2 equations
x + y = 4 → (1)
y = 3x → (2)
Substitute y = 3x into (1)
x + 3x = 4
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 into (2) for corresponding value of y
y = 3 × 1 = 3
solution is (1, 3 )
The salesperson would earn $800 as gross base paycheck
How many hours of did the salesperson achieve?
The salesperson only worked 40 hours of normal time and there is no overtime, which means that the hourly rate remains $10.00 base salary
