What is the solution to the system of equations?
y = 1.5x – 4
y = –x
a. (–1.6, 1.6)
b. (–1.5, 1.5)
c. (1.5, –1.5)
d. (1.6, –1.6)

I believe the correct answer from the choices listed above is option D. The solution to the system of equations given above would be (1.6, –1.6). We can use the substitution method to solve this. We do as follows:

-x = 1.5x – 4
4 = 2.5x
x = 1.6
y = -x = -1.6

I hope this helps you

y= 1.5x - 4

-x= 1.5x - 4

1.5x+x=4

2.5x=4

x=1.6

y= -1.6
