Observe the equations in the following order: 9 × 0 + 3 = 3, 9 × 1 + 4 = 13 Guess: the nth equation (n is a positive integer) should be expressed as?

Observe the equations in the following order: 9 × 0 + 3 = 3, 9 × 1 + 4 = 13 Guess: the nth equation (n is a positive integer) should be expressed as?

9 × 0 + 3 = 3, the first is 9 * 0, then 03 = 10 * 0 + 3
9 × 1 + 4 = 13, the second is 9 * 1, then 13 = 10 * 1 + 3
9 × 2 + 5 = 23, the third is 9 * 2, 23 = 10 * 2 + 3
9 × 3 + 6 = 33, the fourth is 9 * 3, then 33 = 10 * 3 + 3
……
The nth equation is expressed as:
9（n-1)+(n+2)=10（n-1)+3
