Substitute
in the first equation with
from the other equation.
Then you have
Job A pays better
there are roughly 52 weeks in a year so multiply that by 40 to get the total hours worked in a year. = 2,080
2,080 hours worked per year multiplied by the hourly pay 9.95 = 20,696
Job A pays $20,696 per year
Job B only pays $17,500
Answer:
(6, 9)
Step-by-step explanation:
Plug in 2/3x + 5 as y into 7x - 3y = 15
7x - 3(2/3x + 5) = 15
7x - 2x - 15 = 15
Add like terms:
5x - 15 = 15
5x = 30
x = 6
Then, plug in 6 as x into y = 2/3x + 5 to solve for y:
y = 2/3x + 5
y = 2/3(6) + 5
y = 9
So, the solution to the system of equations is (6, 9)
