2x + 8 = 12
2x = 12 - 8
2x = 4
x = 2
Question becomes is x = 2 ?

(1) 2x + 10 = 14
2x = 14 - 10
2x = 4
x = 2
Sufficient

(2) 3x + 8 = 14
3x = 14 - 8
3x = 6
x = 2
Sufficient

Hence, D.

OA: D

Does \(2x + 8 = 12\)? reduces to Is \(x=2?\)

(1) \(2x + 10 = 14\)
\(2x=14-10\)
\(x = \frac{4}{2}=2\)
Is \(x=2?\) : yes
Statement \(1\) alone is sufficient.

(2)\(3x + 8 = 14\)
\(3x = 14 -8\)
\(x =\frac{6}{3} =2\)
Is \(x=2?\) : yes
Statement \(2\) alone is sufficient.

Question is basically asking what is x?

From both the option we can derive the value of x.

Hence, option D is the answer.

Solve the question stem to get x=2

And then test both the options.
