Question

if (11, 3x- y) = (5x+2y , 11/2), find x and y​

Answer 1

Answer:

on comparing x-axis

11 = 5x+2y (eq1)

on comparing Y-axis

11/2 = 3x-y

11 = 6x -2y ( eq 2)

adding eq 1 and eq 2

6x - 2y = 11

5x + 2y =11

——--—-——

11x = 11

x= 11/11

x = 1

put x = 1 in eq 1

5 * 1 + 2y = 11

5 + 2y =11

2y = 11 - 5

y = 6/2

y = 3
