Question

Y=-4x.-3
y= -2x + 1
What is y and x?

Answer 1

you would equal the equations together then solve for a variable.

-4x - 3 = -2x + 1

-4x + 2x = 1 + 3

-2x = 4
—— —-
-2 -2

x = -2

then take that x value and substitute it into any one of the equations.

Equation #1
y = -4(-2) -3
= 8 - 3
= 5

Equation #2
y = -2(-2) + 1
= 4 + 1
= 5

Answer 2

The value of x=-2 and the value of y=5

Explanation:

we have

Y=-4x-3 -----> equation A

y= -2x + 1 -----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The intersection point is (-2,5)

see the attached figure

therefore

The value of x=-2 and the value of y=5
