-4х + 9y = 9
x - Зу = -6

x = 9    y = 5

Step-by-step explanation: I like to use elimination for problems like these. Start by multiplying everything in the second equation (x - 3y = -6) by 4. Your equation should then look like this: 4x - 12y = -24

Now add the two equations as if they were two numbers:

-4x + 9y = 9

4x - 12y = -24

Your x's will cancel out and 9y + -12y = -3y and 9 + -24 = -15. This will make your new equation look like:

-3y = -15

Divide both sides by -3 and you get that y = 5

Substitute 5 in for y for any of the original given equations and solve:

-4x + 9y = 9

-4x + 9(5) = 9

-4x + 45 = 9

-4x = -36

x = 9

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

nope lol
