The solution to the simultaneous equations 5X - Y = 10 and 10X + Y = 35 is
A) X = 15, Y = 0.
B) X = 3, Y = 5.
C) X = 5, Y = 3.
D) None of these.

To solve this system of equations, we can use the method of elimination. Adding the two equations gives us:

5X - Y + 10X + Y = 10 + 35
15X = 45
X = 3

Substituting X = 3 into either equation gives us:

10(3) + Y = 35
Y = 5

Therefore, the solution is X = 3 and Y = 5, which corresponds to choice B.
