Y = x-4

-4x +3y = -3


Replace y in the second equation with the first equation:


-4x +3(x-4) = -3

Simplify:

-4x + 3x-12 = -3

Combine like terms:

-x -12 = -3

Add 12 to each side:

-x = 9

Divide both sides by -1:

x = -9


Since -9 is only in one answer choice, the answer is (-9, -13)

Answer:

(-9,-13)

Step-by-step explanation:

y = x-4

-4x+3y = -3

Substitute y =x-4 into the second equation

-4x +3(x-4)= -3

Distribute

-4x+3x-12 = -3

Combine like terms

-x -12 = -3

Add 12 to each side

-x -12+12 = -3+12

-x = 9

Multiply by -1

-1*-x = 9*-1

x=-9

Now we need to find y

y= x-4

y = -9-4

y=-13
