Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
x + 3y = - 1 → (1)
- 2x - 3y = 5 → (2)
Adding the 2 equations term by term will eliminate the y- term
- x + 0 = 4
- x = 4 ( multiply both sides by - 1 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
- 4 + 3y = - 1 ( add 4 to both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (- 4, 1 )

Answer:
b,y and m and x
Step-by-step explanation:
Step-by-step explanation:
1 dozen = 12 pears
12 pears = $36
1 pear = 36/12 = $3
Total Cost of Pears = No. of pears x price of 1 pear
= (5x12) x 3
= 60 x 3
= $180
Sale of Pears = Price per pear x (Total Pears bought - Rotten Pears)
= $4.50 x (5x12-7)
= $4.50 x 53
= $238.50
Profit/Loss = Sale of Pears - Total Cost of Pears
= $238.50 - $180
= $58.50
Ariana made a profit of $58.50.
Here's the equation I am going to use:
14(x)+7(x)
x= the number of t-shirts I want to buy (11)
14(11)+7(11)= 231$
$231 is your answer.
I hope this helped you!
