BRAINLIEST GUARANTEED. Please Answer and show work. I'm not sure if it's correct though.

They all look right but i'm not sure about the last one?

Step-by-step explanation:

A) False

B) True

C) True

D) False Solution is actually (-3, -3)

work below

Note: Used Elimination Method

Multiply the first equation by -2,and multiply the second equation by 1.

−2(−2x+y=3)

1(3x+2y=−15)

Becomes:

4x−2y=−6

3x+2y=−15

Add these equations to eliminate y:

7x=−21

Then we solve 7x = −21 for x:

7x = −21

7         7

(we Divide both sides by 7)

x=−3

Now that we've found x let's put it back in to solve for y.

Put down an original equation:

−2x+y=3

Substitute−3 for x in−2x+y=3:

(−2)(−3)+y=3

y+6=3(Simplify both sides of the equation)

y+6+−6=3+−6(Add -6 to both sides)

y= −3

Solution

(-3, -3)

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
