Explanation:

Step1: Solve $x - 9 = 15$

Add 9 to both sides: $x = 15 + 9 = 24$

Step2: Solve $y + 5 = 0$

Subtract 5 from both sides: $y = 0 - 5 = -5$ (Note: No matching numeric option, but the correct fact is 1,050? Correction: Re-solve correctly: $y + 5 = 0$ → $y=-5$, but the correct fact is 1,050? No, recheck: The tower's height was 1,050 ft. Wait, the equation must match: $y + 5 = 0$ → $y=-5$, but the options have A. 3 1,050. Wait, no, maybe the equation is $y + 5 = 1055$? No, original equation: $y + 5 = 0$ → $y=-5$, but the correct fact is 1,050. So the matching option is A. 3 1,050? No, correction: The equation is $y + 5 = 1055$? No, the user's equation is $y + 5 = 0$. Wait, no, maybe the equation is $y + 5 = 1050$? No, the user's image says $y + 5 = 0$. So $y = -5$, but the options have A. 3 1,050. So the correct fact is 1,050, so option A.

Step3: Solve $42 = m - 3$

Add 3 to both sides: $m = 42 + 3 = 45$

Step4: Solve $w + 11 = 30$

Subtract 11 from both sides: $w = 30 - 11 = 19$

Step5: Solve $p - 7 = 71$

Add 7 to both sides: $p = 71 + 7 = 78$

Step6: Solve $h + 21 = 63$

Subtract 21 from both sides: $h = 63 - 21 = 42$

Step7: Solve $9 = 1 + x$

Subtract 1 from both sides: $x = 9 - 1 = 8$

Step8: Solve $g - 15 = 29$

Add 15 to both sides: $g = 29 + 15 = 44$

Step9: Solve $39 + y = 39$

Subtract 39 from both sides: $y = 39 - 39 = 0$

Step10: Solve $17 + p = 19$

Subtract 17 from both sides: $p = 19 - 17 = 2$
