Answer:
(-2, 3)
Step-by-step explanation:
4x + 5y = 7
3x - 2y = -12
Let's solve this by elimination. We want to eliminate one variable at a time. This means we need to multiply the equations to create a common multiple to cancel out a variable.
Let's work with y.
5y and -2y: For these values to cancel out, we need to multiply each term to create a common multiple.
2(4x + 5y = 7)
5(3x - 2y = -12)
Multiply.
8x + 10y = 14
15x - 10y = -60
Eliminate.
23x = -46
Divide both sides by 23.
x = -2
Now that we know x, let's plug it back into one of equations to find y.
4x + 5y = 7
4(-2) + 5y = 7
Multiply.
-8 + 5y = 7
Add.
5y = 15
Divide.
y = 3
Now we know x and y; let's plug both back into the equation we have not checked yet.
3x - 2y = -12
3(-2) - 2(3) = -12
Multiply.
-6 - 6 = -12
Subtract.
-12 = -12
Your solution is correct.
(-2, 3)

Choose the correct answer from your choices.
Step-by-step explanation:
First, we find the price of the turkey by multiplying the weight of turkey by the price per pound.
2.1 pounds of turkey at the deli. The price of the turkey was 2.87 per pound.
2.1 lb * 2.87 $/lb = $6.03
Then, we find the price of the ham by multiplying the weight of ham by the price per pound.
She also bought 4.8 pounds of ham. The price of the ham was 2.11 per pound.
4.8 lb * 2.11 $/lb = $10.13
Now we add the two prices together.
$6.03 + $10.13 = $16.16
The total price was $16.16
