9 - 0.75(x+8) - 5 = -2
9-.75x-6-5=-2
-.75x=-2-9+6+5
-.75x=0
x=0/-.75
x=0 ans.
Proof:
9-.75(0+8)-5=-2
9-6-5=-2
-2=-2
-----------------------------------------
15 - 8(x-6)
-------------- = -2.25
4
15-8(x-6)=-2.25*4
15-8x+48=9
-8x=9-15-48
-8x=-54
x=-54/-8
x=6.75 ans.
Proof:
(15-8(6.75-6))/4=-2.25
(15-8*.75)=4*-2.25
15-6=9
9=9
