Question

What is the solution to the system of equations?

y = 1.5x – 4

y = –x

(–1.6, 1.6)
(–1.5, 1.5)
(1.5, –1.5)
(1.6, –1.6)

Answer 1

Answer:

(1.6,-1.6)

Step-by-step explanation:

putting value of y in equation:

y=1.5x -4 (y= -x) -EQ 1

-x = 1.5x -4

-1.5x - 1 x = -4

-2.5x = -4

x = 4/2.5

x=8/5 = 1.6

putting value of x in EQ 1

y=1.5 (1.6) -4

y = 2.4 - 4

y = -1.6
