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

Answer:

The answer is 8/5  or 8 out of 5.

Step-by-step explanation:  

In order to solve this you need to first add the number of envelopes together to get the sum of how many envelopes there are, 1 + 3 + 2 + 2 = 8. Next you add the amount of blue and green envelopes together 3 + 2 = 5. The total number of envelopes is 8, and 5 out of the 8 are green or blue, therefore you will have a 8 out of 5 chance of picking one of those colors.
