Answer:
x = 1.153846153846154
y = -1.923076923076923
Step-by-step explanation:
Multiply 7x - y = 12 by -4 and then add it to 2x - 4y = 10
2x - 4y = 10
+(-4( 7x - y = 12))
-26x = -30

x = 1.153846153846154
Then plug in x to get y.
2(1.153846153846154) - 4y = 10
2.307692307692308 - 4y = 10
-2.307692307692308 -2.307692307692308
-4y = 7.692307692307692

y = -1.923076923076923
Answer:
x = $3.50; y = $2.25
Step-by-step explanation:
First, come up with your two equations where x= price of walnuts and y= price of chocolate chips: 8x + 4y = 37 and 3x + 2y = 15. Solve the first equation.
3x + 2y = 15
3x = 15 - 2y
x = (15 - 2y)/3
Plug in the answer to your second equation.
8(15 - 2y)/3 + 4y = 37
(120 - 16y)/3 + 4y = 37
120 - 16y + 12y = 111
120 - 4y = 111
-4y = -9
y = 2.25
Plug in your answer to find <em>x.</em>
3x + 2(2.25) = 15
3x + 4.5 = 15
3x = 10.5
x = 3.5
Check your equation.
1) 3(3.5) + 2(2.25) = 15
10.5 + 4.5 = 15
15 = 15
2) 8(3.5) + 4(2.25) = 37
28 + 9 = 37
37 = 37
