The linear combination method gives a solution of (-4, 2) for which of these systems of linear equations?

3x+ 13y 14
Bx+11y-2

4x+5y - 12
Bx+3y=-4

5x+4y - 12
7x+8y - 12

10x+3y-B
17x+By – 10

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
