Examaple 4 Find the values of x, y and z so that the vectors ๐‘Ž โƒ— = x๐‘– ฬ‚ + 2๐‘— ฬ‚ + z๐‘˜ ฬ‚ and ๐‘ โƒ— = 2๐‘– ฬ‚ + y๐‘— ฬ‚ + ๐‘˜ ฬ‚ are equal. ๐‘Ž โƒ— = x๐‘– ฬ‚ + 2๐‘— ฬ‚ + ๐‘ง๐‘˜ ฬ‚ ๐‘ โƒ— = 2๐‘– ฬ‚ + y๐‘— ฬ‚ + ๐‘˜ ฬ‚ Since ๐‘Ž โƒ— = ๐‘ โƒ— Comparing corresponding components, Thus, x = 2 , y = 2 & z = 1 ๐‘Ž โƒ— = x๐‘– ฬ‚ + 2๐‘— ฬ‚ + ๐‘ง๐‘˜ ฬ‚ ๐‘ โƒ— = 2๐‘– ฬ‚ + y๐‘— ฬ‚ + ๐‘˜ ฬ‚ Since ๐‘Ž โƒ— = ๐‘ โƒ— Comparing corresponding components, Thus, x = 2 , y = 2 & z = 1
