Solve the system of equations

12x-5y=-20
Y=x+4
X=
Y=

To solve this system of equations, we will substitute the value of y from the second equation into the first equation.

From the second equation, we have y = x + 4.

Substituting this into the first equation, we get:
12x - 5(x + 4) = -20
12x - 5x - 20 = -20
7x - 20 = -20
7x = 0
x = 0

Now, substitute the value of x back into the second equation to solve for y:
y = 0 + 4
y = 4

Therefore, the solution to the system of equations is:
x = 0
y = 4
