Step-by-step explanation:

Systematic solution:

\left \{ {{x+y=255} \atop {x+5y=855}} \right.

\left \{ {x=255-y} \atop {x+5y=855} \right.

255-y+5y=855

4y=600

y=150

x=255-150=100

Remark

The only points that can lie on the y axis are a and d. There has to be a zero someplace. But the question is where?


The answer is in the graph below. (0,6) is in red and it is on the y axis.

(6,0) is blue and is on the x axis.


So if you want a point to lie on the y axis, the answer is that the x part of the point must be 0.
