Ex 4.1, 7 Find values of x, if (ii) |โ– 8(2&3@4&5)| = |โ– 8(๐‘ฅ&3@2๐‘ฅ&5)| Now, given that |โ– 8(2&3@4&5)| = |โ– 8(๐‘ฅ&3@2๐‘ฅ&5)| Putting values โ€“2 = โ€“ x 2 = x x = 2 Hence value of x is 2 Calculating |โ– 8(2&3@4&5)| = 2(5) โ€“ 4 (3) = 10 โ€“ 2 = โ€“2 Calculating |โ– 8(๐‘ฅ&3@2๐‘ฅ&5)| = x(5) โ€“ 2x (3) = 5x โ€“ 6x = โ€“x
