Answer:

(2,6)

Step-by-step explanation:

x-y=-4 -----> Get the one of the variables by themselves

x=-4+y -----> All i did was adding the y to the the other side to get x by itself

Now all you do is to substitute the in the equation into the other equation

x=-4+y --------------> 6(-4+y)-4y=-12

Then solve

Now since you have your y now all you need to do is to do the same thing

Substitute the y in for the other equation

Then there you go

What is the value of the expression -225 divided by -15? –25 –15 15 25

choli [55]

-225/-15 will give us a positive answer since we are dividing by two negative values, so we can rule out answers 1 and 2 first off.

then we solve to find the answer -225/1*-1/15 = 15

hope this helps! thanks!
