Choose an option
-
Ax + =
-
B= x +
-
C+ x =
-
D= + x
Answer
Correct Answer: = x +
Explanation
Introduction / Context:We must choose three symbols that, when substituted in order, yield a correct equality. The placement of “=” divides left and right sides.
Given Data / Assumptions:
- Template: 24 {s1} 4 {s2} 5 {s3} 4
- Try options where “=” yields a sensible split.
Concept / Approach:Testing Option B produces an immediately true equality.
Step-by-Step Solution:
Option B: s1 = “=”, s2 = “×”, s3 = “+”. Statement becomes 24 = 4 × 5 + 4.Right side: 4 × 5 + 4 = 20 + 4 = 24.Hence balanced.Verification / Alternative check:Other placements of “=” do not simplify to an identity with remaining symbols.
Why Other Options Are Wrong:
- They evaluate to values not equal to 24.
Common Pitfalls:
- Forgetting that multiplication precedes addition on the right side.
Final Answer:= x +
