What is the X and Y value?

x = 3, y = -6

Step-by-step explanation:

-6x - y = -12 (1)

4x + y = 6 (2)

Add (1) and (2)

-2x = -6

x = 3

4x + y = 6

12 + y = 6

y = -6

x = 3, y = -6

Step-by-step explanation:

solving by elimination

-6x - y = -12 (1)

4x + y = 6  (2)

(1)+(2) ⇒ -2x = -6 ⇒ x = 3

now ,we substitute x by 3 in the second equation then we get

4(3) + y = 6 ⇔ 12 + y = 6 ⇔ y = -6

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
