Step-by-step explanation:
Hii ☺ !!
Here is your answer ✓ ✓ ✓ ✓
3x - y = 27 ---------(1)
And,
3x + y = 243 ----------(2)
From equation (1) we get
3x - y = 27
3x = ( 27 + y)
x = ( 27 + y /3) ---------(3)
Putting the value of X in equation (2) , we get
3x + y = 243
3 × ( 27 + y /3) + y = 243
27 + y + y = 243
2y = 243 - 27
2y = 216
y = 216/2
y = 108
Putting the value of y in equation (3 ) , we get
x = ( 27 + y /3)
x = ( 27 + 108/3) = 135/3
x = 45
Hence,
X = 45 and Y = 108
