Put X-4 to where Y is in the first equation. So;
X-4= -X-6
Then solve to find X;
Add 6 to both sides;
X+2=-X
Subtract X from both sides;
2=-X-X
2= -2X
Divide both side by -2;
-1=X

Answer:

x = 11 ,

<APT = 6x + 1 ➡ 67°

<PTA = 9x - 24 ➡75°

bekas [8.4K]

Answer:

(5 , 0)

Step-by-step explanation:

7 * (−9y+4x−20)=0

9 * (−7y+16x−80)=0

-63y + 28x -140 = 0 ......a

-63y + 144x -720 = 0 .....b

b-a:  116x - 580 = 0

116x = 580

x = 5

y = (4x-20)/-9 = 0/-9 = 0
