Answer:
(5,-1) or x=5 y=-1
Step-by-step explanation:
I used the substitution method to solve this!
<em>1. Pick one of your equations and solve for one of the variables. I chose the first equation and solved for x.</em>
x-2y=7
(Move the -2y to the other side of the equation in order to get the x by itself. You do the opposite, so it becomes +2y.)
x=2y+7
<em>2. Now take your second equation and plug in what you got for x into the x variable.</em>
2(2y+7)+5y=5
(Multiple 2 by everything inside of the parentheses.)
4y+14+5y=5
(We want to get the y by itself, so move the 14 to the other side.)
4y+5y=-14+5
(Combine all the like terms.)
9y=-9
(Divide the 9 from the y. What you do to one side you must do to the other.)
y=-1
<em>3. Since you have one variable solved for. Now take the first equation and plug in your y.</em>
x-2(-1)=7
(Multiple -2 by -1)
x+2=7
(Move the 2 to the other side in order to get the x by itself.)
x=5
<em>4. If needed, plug in your x and y values into the equations in order to check your answer.</em>
Hope this could help!
Complete question :
grocery store was having a sale. Darla had $15 in her wallet. She planned to purchase 2 gallons of fruit juice, 3 bags of chips, and a box of cupcakes. Item Sale Price Gallon of fruit juice $3.50 for first gallon, 50% off the second gallon Bag of Chips 2 for $5 or $2.65 each Box of cupcakes $4.79 How much would Darla pay for her groceries before tax? Show your work.
Answer:
$17.69
Step-by-step explanation:
Amount had = $15
Items to be purchased = 2 gallons of fruit juice, 3 bags of chips, and a box of cupcakes.
First gallon of juice = $3.50
Second gallon = 0.5 * 3.50 = $1.75
3 Bags of chips = $2.65 + $5 = $7.65
A box of cupcake = $4.79
Total cost before tax = $(3.50 + 1.75 + 7.65 + 4.79)
= $17.69
