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
