Answer 2

Answer:

x= 1.6

y= - 1.6

Step-by-step explanation:

$y = 1.5x - 4$

$y = -x$

WE solve for x and y using substitution method

LEts plug in -x for y in the first equation

$y = 1.5x - 4$

$-x = 1.5x - 4$

Subtract 1.5x on both sides

$-2.5x=- 4$

Divide both sides by -2.5

x= 1.6

Now plug in 1.6 for x in y=-x

y= - 1.6
