To solve this system of equations, we can substitute the expression for X in terms of y from the first equation into the second equation:
2(6y - 3) + 7y = 13
12y - 6 + 7y = 13
19y - 6 = 13
19y = 19
y = 1
Now substitute y = 1 into the first equation to find the value of X:
X = 6(1) - 3
X = 3
Therefore, the solution to the system of equations is X = 3 and y = 1.
