4x - 3y = -28<br>x + 5y = 39 cant seem to be able to figure the answer for this​
Rus_ich [418]

value of x = -1 and value of y=8

Step-by-step explanation:

We need to solve the system of equations:

4x - 3y = -28\,\,\,(1)\\x + 5y = 39\,\,\,(2)

Multiply eq(2) with 4 and subtract with eq(1)

4x-3y=-28\\4x+20y=156\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-23y=-184\\y=\frac{-184}{-23}\\y=8

So, value of y=8

Now, finding value of x by putting value of y in equation 2

x+5y=39\\x+5(8)=39\\x+40=39\\x=39-40\\x=-1

So, value of x = -1

value of x = -1 and value of y=8

nevsk [136]
Sorry I am late but the I think it is this, I don’t know the answer but here is what I know. answer is: Imagine a rectangle that has one vertex at the origin and the opposite vertex is A. Now that you can see the image of A(3,4) under the rotation is A’(-4,3). It is easier to rotate the points that lie on the axes, and these help us find the image of A.
POINT: (3,0) (0,4) (3,4)
