Question

Which equation is true if b = 2?

2b + 24 = 30
3b - 2 = 4
B + 4 = 8
2b - 3 = 0

Answer 1

2nd equation is correct.

Explanation:

1) 2b + 24 = 30

→ 2(2) + 24 = 30

→ 4 + 24 = 30

→ 28 ≠ 30

Hence, it is false.

2) 3b - 2 = 4

→ 3(2) - 2 = 4

→ 6 - 2 = 4

→ 4 = 4

Hence, it is true.

3) B + 4 = 8

→ 2 + 4 = 8

→ 6 ≠ 8

Hence, it is false.

4) 2b - 3 = 0

→ 2(2) - 3 = 0

→ 4 - 3 = 0

→ 1 ≠ 0

Hence, it is false.
