Answer:
The value of x is 4 and y is (-9)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
<h3><u>To </u><u>Find</u>;</h3>
- Value of x
- Value of y
- By Elimination Method
Now, Name the equation
x + 2y = -14 ...(1)
x – y = 13 ...(2)
Now,
x + 2y = -14
x – y = 13
<u>– + –</u>
3y = -27
y = -9
Now, put the value of y in equation 2
x – y = 13
x – (-9) = 13
x + 9 = 13
x = 4
Thus, The value of x is 4 and y is (-9)
<h3>
<u>For </u><u>Verification</u>;</h3>
x + 2y = -14
4 + 2(-9) = -14
4 – 18 = -14
-14 = -14
x – y = 13
4 – (-9) = 13
4 + 9 = 13
13 = 13
Hence, L.H.S = R.H.S
