Answer:

The solution is the point (0.5,-3)

Step-by-step explanation:

we have

[tex]y=4x-5[/tex] ----> equation A

[tex]y=-3[/tex] ----> equation B

Solve the system by substitution

Substitute equation B in equation A

[tex]-3=4x-5[/tex]

Solve for x

Adds 5 both sides

[tex]-3+5=4x[/tex]

[tex]2=4x[/tex]

Divide by 4 both sides

[tex]x=0.5[/tex]

therefore

The solution is the point (0.5,-3)

Verify your  answer using the graph

using a graphing tool

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (0.5,-3)

therefore

The solution is the point (0.5,-3)

Answer:

Since y= -3, just put that in the equation.

-3 = 4x - 5

+5         +5

2 = 4x

/4    /4

x=1/2
