The constants $12$ and $5$ are like terms: $12 + 5 = 17$. The term $p$ stays the same, so the expression is equivalent to $p + 17\textsf{.}$

Combine $x$-terms: $8x + 8x = 16x$. Combine constants: $2 - 1 = 1$. Result: $16x + 1$.

The terms $2y$ and $3y$ are like terms: $2y + 3y = 5y$. The constant $6$ stays the same, so the expression is equivalent to $5y + 6\textsf{.}$

Combine: $-6x + -2x = -8x$, $-8 + -7 = -15$. Result: $-8x - 15$.

The terms $4x$ and $x$ are like terms: $4x + x = 5x$. The constant $9$ stays the same, so the expression is equivalent to $5x + 9\textsf{.}$

Distribute 2: $2 \cdot 4x + 2 \cdot -3 = 8x - 6$.

The constants $10$ and $-4$ are like terms: $10 - 4 = 6$. The term $t^{2}$ stays the same, so the expression is equivalent to $t^{2} + 6\textsf{.}$

Combine: $-3x + 5x = 2x$, $-10 + 2 = -8$. Result: $2x - 8$.
