Solve the system of equations.
3r + 4y = -23
X= 3y + 1

Step-by-step explanation:

/| x-(4*y)-3 = 0| 3*y-x+1 = 0

We try to solve the equation: x-(4*y)-3 = 0

x-4*y-3 = 0 // - x-3

-4*y = -(x-3) // : -4

y = (-(x-3))/(-4)

y = (3-x)/(-4)

We insert the solution into one of the initial equations of our system of equations

We get a system of equations:

/| 3*((3-x)/(-4))-x+1 = 0| y = (3-x)/(-4)

(3*(3-x))/(-4)-x+1 = 0

1-1/4*x-9/4 = 0

-1/4*x-5/4 = 0

-1/4*x-5/4 = 0 // + 5/4

-1/4*x = 5/4 // : -1/4

x = 5/4/(-1/4)

x = -5

We insert the solution into one of the initial equations of our system of equations

For y = (3-x)/(-4):  

y = (3+5)/(-4)

y = 8/(-4)

y = -2

We get a system of equations:

/| y = -2| x = -5
