Answer 1

I attached a photo of the work. I hope it helps!

Answer 2

x= 1.6

y= - 1.6

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
