Q. Select all of the equations below that are equivalent to:\newline3=b+153 = b + 15\newlineUse properties of equality.\newlineMulti-select Choices:\newline(A) 8=5+b+158 = 5 + b + 15\newline(B) 6=3+b+156 = 3 + b + 15\newline(C) 9=b+15+69 = b + 15 + 6\newline(D) 20=17+b+1520 = 17 + b + 15
  1. Simplify equation for b: Simplify the original equation to isolate bb: 3=b+153 = b + 15. Subtract 1515 from both sides to find bb. Calculation: 315=b3 - 15 = b, b=12b = -12
  2. Check choice (A): Check each choice to see if substituting b=12b = -12 results in a true statement. Start with choice (A): 8=5+b+158 = 5 + b + 15. Substitute b=12b = -12: 8=512+158 = 5 - 12 + 15. Calculation: 8=88 = 8
  3. Check choice (B): Check choice (B): 6=3+b+156 = 3 + b + 15. Substitute b=12b = -12: 6=312+156 = 3 - 12 + 15. Calculation: 6=66 = 6
  4. Check choice (C): Check choice (C): 9=b+15+69 = b + 15 + 6. Substitute b=12b = -12: 9=12+15+69 = -12 + 15 + 6. Calculation: 9=99 = 9
  5. Check choice (D): Check choice (D): 20=17+b+1520 = 17 + b + 15. Substitute b=12b = -12: 20=1712+1520 = 17 - 12 + 15. Calculation: 20=2020 = 20
