m=5p+8
m=-10p+3
Set these 2 equations equal'
5p+8=-10p+3 solve for p.
5p+10p=3-8
15p=-5
p=-5/15
p=-1/3 ans.
m=5*1/3+8
m=5/3+8
m=5/3+24/3=29/3 or 9 2/3 qns
Proof:
29/3=-10*-1/3+3
29/3=10/3+3
29/3=10/3+9/3
29/3=29/3

m=5*-1/3+8
m=-5/3+8
m=-5/3+24/3=19/3 or 6 1/3 qns
Proof:
19/3=-10*-1/3+3
19/3=10/3+3
19/3=10/3+9/3
19/3=19/3
