Let d be number of drinks and b be number of buckets of chips
2d+b=11 so we can say b=11-2d
3d+2b=19 and using b from above in this we get:
3d+2(11-2d)=19
3d+22-4d=19 subtract 22 from both sides
-d=-3 divide both sides by -1
d=3, and from earlier b=11-2d so
b=11-6=5
So a bucket of chips cost $5 and a drink costs $3
Answer:
x=1
y=-4
Step-by-step explanation:
4x+y=0 -> y= -4x
2(-4x)+x=-7
-8x+ x=-7
-7x=-7
x=-7/-7=1
y=-4 . 1 = -4
Caleb - c
Kyras - k
k+c=37
c=2k-4
k+(2k-4)=37
3k=41
k=41/3= ~13.67 years old
c=37-k
c=(111-41)/3
c=70/3=~23.33 years old
