Aldo and Shamir bought 11 shirts combined. Aldo bought 4 less than twice as many shirts as Shamir. SOLVE to find how many shirts each person bought

Answer 1

Let's assume Shamir bought x shirts.
According to the problem, Aldo bought 4 less than twice as many shirts as Shamir, so Aldo bought (2x-4) shirts.
The total number of shirts bought is the sum of the number of shirts bought by Aldo and Shamir, which is (2x-4) + x = 11.
Combining like terms, we get 3x - 4 = 11.
Adding 4 to both sides of the equation, we get 3x = 15.
Dividing both sides of the equation by 3, we get x = 5.
Therefore, Shamir bought 5 shirts and Aldo bought (2*5- 4) = 6 shirts.
