To solve this system of equations, we can use the substitution method.

From the first equation:

X = 7y

Now substitute X = 7y into the second equation:

12(7y) + y = 17
84y + y = 17
85y = 17
y = 17/85
y = 0.2

Now substitute y = 0.2 back into X = 7y:

X = 7(0.2)
X = 1.4

Therefore, the solution to the system of equations is X = 1.4 and y = 0.2.
