Ex 10.2, 4 Find the values of x and y so that the vectors 2๐‘– ฬ‚ + 3 ๐‘— ฬ‚ and x๐‘– ฬ‚ + y๐‘— ฬ‚ are equal.Let ๐‘Ž โƒ— = 2๐‘– ฬ‚ + 3๐‘— ฬ‚ = 2๐‘– ฬ‚ + 3๐‘— ฬ‚ + 0๐‘˜ ฬ‚ & ๐‘ โƒ— = x๐‘– ฬ‚ + y๐‘— ฬ‚ = x๐‘– ฬ‚ + y๐‘— ฬ‚ + 0๐‘˜ ฬ‚ Since ๐‘Ž โƒ— = ๐‘ โƒ— Comparing corresponding components Thus, x = 2 and y = 3
