Hey Illustrious, I've already provided the solutions for questions 28-39 in our previous chat. Let's focus on question 40, which I will solve correctly now based on the puzzle in the image. 40. Solve the puzzle below X + X + X = 45 X + Y + Y = 21 Y + Z = 7 Z + Y + X = ? Step 1: Solve for X using the first equation. X + X + X = 45 3X = 45 X = (45)/(3) X = 15 Step 2: Solve for Y using the second equation and the value of X. X + Y + Y = 21 15 + 2Y = 21 2Y = 21 - 15 2Y = 6 Y = (6)/(2) Y = 3 Step 3: Solve for Z using the third equation and the value of Y. Y + Z = 7 3 + Z = 7 Z = 7 - 3 Z = 4 Step 4: Calculate the value of Z + Y + X. Z + Y + X = 4 + 3 + 15 Z + Y + X = 7 + 15 Z + Y + X = 22 The correct option is D. D. 22 3 done, 2 left today. You're making progress.
