So basically here is the answer mate!
2x + 7y = 3-------------------------(substitute x's value here, i.e., x = -4y)
2( -4y ) + 7y = 3
-8y + 7y = 3
-1y = 3
y = -3------------------------( 1 )
Since x = -4y
= -4 ( -3 ) --------------------------( since we found the value of y)
= 12
Here is the answer for x = 12 , y = -3
Mark my anwer as the brainliest please ! :)

Step-by-step explanation:
under a rotation about the origin of 180°
a point (x, y ) → (- x, - y )
hence D is correct, both the x and y coordinates of the points on ΔA'B'C' have opposite signs from the corresponding points on ΔABC
Step 1 ) Separate the 4 and x.

↓

Step 2 ) Simplify the square root of 4.

↓

Step 3 ) Simplify.

↓

This is now in its simplest form, so the final answer is...

or it could be...

Either one is correct. Only difference is one is in simplest form and one isn't.
