So all you have to do is divide every thing by 6 and then add two of the answer together I'll show you.
450÷6=75 now add 75+75=150 now do 450- 150= 300 you need 300g of cream cheese.
90÷6=15 now add 15+15=30 now do 90- 30=60 you need 60g of butter
120÷6=20 now add 20+20=40 now do 120- 40=80 you need 80g of castor oil
6÷6=1 now add 1+1=2 now do 6- 2=4 you need 4 eggs
I hope that was fast enough
The answer is X=5
-2x-= -10-5
-3x=-15

Answer:
B. Solve each equation for a variable
Is (-1,13) a solution of the system: Yes it is x =1, y= 13
Step-by-step explanation:
-4x=30-2y
- 15 = - 2y + 11x
-4x=30-2y
-2y+4y = -30-------------------i
- 2y + 11x= - 15 ---------------ii
make x the subject of formula in equ i
-4x=30-2y
x= (30-2y)/-4
insert x= (30-2y)/-4 in equ ii
- 2y + 11x= - 15
-2y+ 11((30-2y)/-4)= -15
-2y+(330-22y)/4 = -15
-8y+330-22y/4 = -15
-8y-22y+330/4= -15
cross multiply
-30y+330 = 4x-15 = -60
-30y = -60-330
-30y =--390
y= -390/-30 = 13
if y = 13
x = (30-2y)/-4 = (30-2x13)/-4 = (30-26)/4 = 4/4 = 1
x=1 , y=13
