MCQ
If $8 x-13=25+16 x$, then $x$ is
- A$0$
- ✓$-\frac{19}{4}$
- C2
- D-4
✓
Answer
Correct option: B.
$-\frac{19}{4}$
(B) $-\frac{19}{4}$
Hint We have,
$8 x-13=25+16 x$
$\Rightarrow \quad 8 x-16 x=25+13\quad$ [transposing $16 x$ to LHS and $-13$ to RHS]
$\Rightarrow \quad-8 x=38$
$\Rightarrow \quad x=\frac{38}{-8} \quad$ [dividing both sides by -8]
$\therefore \quad x=\frac{-19}{4}$
