Question

Find the solution to the system of equations. You can use the interactive graph below to find the solution. y=-4x-3 y=-2x+1 x= y=

Answer 1

(-2, 5)

Explanation:

I will assume that your system is

y = -4x - 3

y = -2x + 1

Multiplying the second equation by -2 results in

y = -4x - 3

-2y = 4x - 2

combining these two equations eliminates x temporarily:

-y = -5, so that y must be 5.

Substituting 5 for y in the second equation, we get:

5 = -2x + 1, or

4 = -2x, which results in x = -2

and so the solution is (-2, 5)

Answer 2

The solution is: x = -2, y = 5

In solving system of linear equations problems.

The system of equations is:

y = -4x - 3

y = -2x + 1

The solution is

x = -2, y = 5

You can also see the solution graphically by plotting the equations.
