Answer 1

Answer:

-63

Step-by-step explanation:

i hope this helps u

if u want it's explanation then this is the explanation

area of triangle

ABC = 0

1\2(x1(y2-y3)+X2(y3-y1)+x3(y1-y2))=0

here x1=x,y1=2,y2=-4,,x2=-3,x3=7 and y3=-5

x(-4+5)-3(-5-2)+7(2+4) =0

now further solving we will get ,x+21+42=0

x+63=0

x=-63

thank u
