Step-by-step explanation:
5.505 divided by .25
hi
a ( b +c) = a*b +a*c
here a = -3
b = -4x
c = +5
so :
-3 ( -4x +5) = -3*-4x + -3* 5
= -12x + (-15)
= -12x -15
as I cannot add -12x and -15 ( they are two differents sort of figures )
so it's done
Answer:
Step-by-step explanation:3x-y=18
y=27
Therefore 3x-(27)=18
3x=18+27..Nb when the 27 is now being added instead of subtracted.
3x=45
3x/3=45/3 Nb the 3 is now being divided instead of being multiplied.
Therefore X=15
