Answer:
x = -1
y = -2
Step-by-step explanation:
To get y by itself:
3x - y = -1
-y = -1 - 3x
y = 1 + 3x
Solve for x with substitution:
2x = 4(1 + 3x) + 6
2x = 4 + 12x + 6
2x = 10 + 12x
-10x = 10
x = -1
Plug the x value into 3x - y = -1
3(-1) - y = -1
-3 - y = -1
-y = 2
y = -2
Answer:
Her grocery bill was <u>$4.62</u>.
Step-by-step explanation:
There is some mistake in question so the correct question is:
Sherry bought 6 apples at 43¢ per apple. She then bought 4 oranges at 51¢ per orange. How much was her grocery bill?
Now, to find the grocery bill.
As the units are given:
<em>43¢ per apple and </em>
<em>51¢ per orange.</em>
$1 = 100¢.
So, the cost of 6 apples = 
Thus, the cost of 6 apples = $2.58
And the cost of 4 oranges = 
Thus the cost of 4 oranges = $2.04
Now, to get the total grocery bill we add the cost of apples and oranges:


Therefore, her grocery bill was $4.62.
