Cost of each orange is ₹ x. Tina bought 3 oranges. What will be the coefficient of x after calculating the total amount spent by Tina if she had already spent ₹ (6x + 4y)?
9
The price for 3 oranges is ₹ 3x. Tina had already spent ₹ (6x + 4y). So, the total amount spent is ₹ (6x + 4y + 3x) = ₹ (9x + 4y). Hence, the coefficient of x is 9.
