Question

Which ordered pair is the solution to the following system of equations?

y= x - 4
y = -3x

Answer 1

Answer:

(1,-3)

Step-by-step explanation:

Make the two equations equal to each other:

-3x=x-4

** bc they both are equal to y and they have the same ordered pair that make each of the equations true

Then simplify:

-3x=x-4

-3x-x= x-x -4

-4x=-4

x=1

Now you have x, plug it into either of the equations to get y:

y=x-4

y=1-4

y=-3

So the ordered pair would be: (1,-3)
