Answer:
Answer:x = 5
Answer:x = 5 y = 2
Step-by-step explanation:
x +2y = 9......1
2x-y =8........2
2x - y = 8
=> y = 2x-8........3
Putting value of y in equation 1
We get,
x+2(2x-8) = 9
=> x + 4x -16 = 9
=> 5x = 16+9 = 25
=> x = 25/5
=> x = 5
Putting value of x in equation 3
=> y = 2(5)-8
=> Y = 10-8
=> y = 2
