Answer:
(1.6, -1.6)
Step-by-step explanation:
We have the following system of equations:
[tex]y=1.5x - 4[/tex]
[tex]y=-x[/tex]
We have the following system of equations:
To solve the system substitute the second equation in the first one and solve for x
[tex]y=1.5x - 4[/tex]
[tex]-x=1.5x - 4[/tex]
[tex]4=2.5x [/tex]
[tex]2.5x =4[/tex]
[tex]x =\frac{4}{2.5}[/tex]
[tex]x = 1.6[/tex]
Now replace the value of x in one of the two equations and solve for y
[tex]y=-x[/tex]
[tex]y=-1.6[/tex]
The solution is:
(1.6, -1.6)
