Answer:
(1,4)
Step-by-step explanation:
Let y (upper eq) = y (lower eq)
x+3 = 3x+1
(transposing similar numbers)
3x-x = 3-1
2x = 2
then x = 1
substituting x in any of the equation, say
y = x+3
y = 1 +3
y = 4
therefore (1,4)
check again the lower equation
y = 3x + 1
y = 3(1) + 1
y = 4
therefore (1,4)
Answer:
Y=6
Step-by-step explanation:
What it means is that the x is -3, so you take the -3 and plug it into the x.
Y=-1/3(-3)+5.
Y=1+5
Y=6 is your answer.

Answer:
(a) Money spend on each pack will be $0.8
(b) Money send on each pack will be $0.2
Step-by-step explanation:
We have given that Greg spent $4 on 5 packs of spot card
(a) We have to find how much Greg spend on each pack
Cost of each pack will be 
(b) In this case it is said that Greg spent half of money
So money spent by Greg 
And he bought twice of pack than earlier
So number of packs he bought 
So money spend on each pack will be equal to
