**a. Para $$ (0,\square) $$:**

Sustituimos $$ x=0 $$ en la ecuación:
$$
2(0) + y = 12 \quad \Rightarrow \quad 0 + y = 12 \quad \Rightarrow \quad y = 12.
$$

**b. Para $$ (\square, 0) $$:**

Sustituimos $$ y=0 $$ en la ecuación:
$$
2x + 0 = 12 \quad \Rightarrow \quad 2x = 12 \quad \Rightarrow \quad x = 6.
$$

**c. Para $$ (-1,\square) $$:**

Sustituimos $$ x=-1 $$ en la ecuación:
$$
2(-1) + y = 12 \quad \Rightarrow \quad -2 + y = 12 \quad \Rightarrow \quad y = 12 + 2 \quad \Rightarrow \quad y = 14.
$$

**d. Para $$ (5,\square) $$:**

Sustituimos $$ x=5 $$ en la ecuación:
$$
2(5) + y = 12 \quad \Rightarrow \quad 10 + y = 12 \quad \Rightarrow \quad y = 12 - 10 \quad \Rightarrow \quad y = 2.
$$

**e. Para $$ (\square, 6) $$:**

Sustituimos $$ y=6 $$ en la ecuación:
$$
2x + 6 = 12 \quad \Rightarrow \quad 2x = 12 - 6 \quad \Rightarrow \quad 2x = 6 \quad \Rightarrow \quad x = 3.
$$
a. $$ y = 12 $$ b. $$ x = 6 $$ c. $$ y = 14 $$ d. $$ y = 2 $$ e. $$ x = 3 $$

2. Find a missing value that will make each ordered pair be a solurtion to the enveh \( 2 x+y=12 \) a. \( (\mathrm{O}, \square) \) b. \( (\square, 0) \) c. \( (-1, \square) \) d. \( (5, \square) \) e. \( (\square, 6) \)
