Solve for x and y. 3x+8y=20. 5x+3y=23
2 answers:
Answer:
x=4 and y=1
Step-by-step explanation:
Equation 1) 3x+8y=20
Equation 2) 5x+3y=23
Equation 1) 5(3x+8y=20 )
Equation 2) 3(5x+3y=23)
15x+40y=100
15x+9y=69
(Take away 40y from 9y and 100 from 69)
31y = 31
y=1
Substitute y=1 into equation 1)
3x+8=20
(Take away 8 from both sides)
3x=12
(Divide by 3)
x=4
Answer:
Equation 1:
x= -8/3y + 20/3
y= -3/8x + 5/2
Equation 2:
x= -3/5y + 23/5
y= -5/3x + 23/3

Step-by-step explanation:
yes the answer is correct
Answer:
Times it by 40. That is the pattern.
y= 1.25x+6.75
Make 31.75 y because that is the total cost he paid.
1.25x+6.75=31.75
1.25x=25
x=20
So he had 20 refills.
