Three shirts and 2 neckties cost $69. At the same prices, 2 shirts and 3 neckties cost $61. What is the combined cost of one shirt and one necktie?

I realize this is a system of linear equations in 2 variables.

Let s = shirts and n = neckties

I came up with the following two equations:

3s + 2n = 69

2s + 3n = 61

Is this right so far?

I came up with a combined cost of $35.

The right answer is $26. What did I do wrong?

How do I get $26?
