Answer:
I think the answer is... C. No Solution because if you plug in those points for x & y, it has no solution... It is false... so yeah... I'm really really sorry if I'm wrong...
Step-by-step explanation:
x -2y = 4 - 3x + 6y = 12
-2 - 2(4) = 4 - 3(-2) + 6(4) = 12
-2 - 8 = 4 6 + 24 = 12
-10 = 4 30 = 12
x -2y = 4 - 3x + 6y = 12
0 - 2(-2) = 4 - 3(0) + 6(-2) = 12
0 + 4 = 4 0 - 12 = 12
4 = 4 - 12 = 12

<span>The total number of hours worked between Ruby, Isaac, and Svetlana, hard-working friends with great names, is 126 and is equal to r + i + s. 126 = r + i + s. The relationships between Svetlana and Ruby's hours can be written as s = 4r. The relationship between Ruby and Isaac's hours can be written as r = i + 6, or i = r - 6. With these equations, we can return to the original equation and substitute for/ replace Svetlana and Isaac's hours so that the whole equation is in terms of r: 126 = (r) + (r-6) + (4r). Simplify this to 126 = 6r - 6 and then again to 132 = 6r and then at last to 22 = r, the number of hours that Ruby worked. Now returning to the other equations, we can plug in that r value to solve for i -- i = 22 - 6, or 16 hours for Isaac -- and for s -- s = 4(22), or a whopping 88 hours for Svetlana. We conclude that Isaac worked for 16 hours, Ruby worked for 22 hours, and Svetlana worked for 88 hours. 88 + 22 + 16 = 126 hours.</span>
