Question

State a true conclusion. 1) If a ● b = 0, then a = 0 or b = 0 2) 3x = 0

Answer 1

Proposition 1) If a ● b = 0, then a = 0 or b = 0

Proposition 2) 3x = 0

=>  3 = 0 or x = 0

Given that 3 ≠ 0, x must be equal to 0.

Conclusion: x = 0

Answer 2

Answer:

x=0

Step-by-step explanation:

Proposition 1) If a ● b = 0, then a = 0 or b = 0

Proposition 2) 3x = 0

=>  3 = 0 or x = 0

Given that 3 ≠ 0, x must be equal to 0.

Conclusion: x = 0
