Answer:
A) 6x + 6y = 24, Yes, they have the same solution set
Step-by-step explanation:
Let's first start by multiplying the equation by 3:
(2*3)x + (2*3)y = 24
6x + 6y = 24
Now lets find the solution set for both:
6y = -6x + 24
y = -x +4
2y = -2x + 8
y = -x +4
Yes, they have the same solution set
He makes 165$ for 11 hours because he makes 195$ in 13 hours so you divide 195 by 13 to get 15$ the amount he earns per hour. After that you just multiply 15 by 11 to get 165$. Hope this helps:)>
