Answer:
x = 2
y = -1
Step-by-step explanation:
8x + 2y = 14
2x + y = 3
In order to find the number x represents, you have to make the number of y for both equations the same. So:
8x + 2y = 14
(×2) 4x + 2y = 6 (×2)
Then, you can cancel the y off both equations, which will leave:
8x = 14
4x = 6
To find 4x, you have to find the difference between both equations, so you have to:
14 - 6 = 8
Now that the actual number 4x represents is 8, so:
4x = 8
(÷4) x = 2 (÷4)
Now to find y, substitute the letter x with 2:
2x + y = 3
2 (2) + y = 3
4 + y = 3
4 - 3 = -y
1 = -y
(× -) -1 = y (× -)
Answer: x = 2
y = -1
Hope this helps! :)
