Question

If $\frac{x+1}{2}+\frac{4x-1}{4}=5.5$, then find the value of $x$.

• A. $2.5$
• B. $3.0$
• C. $3.5$
• D. $4.0$

Answer 1

The correct option is C $3.5$

Given, $\frac{x+1}{2}+\frac{4x-1}{4}=5.5$

$\Rightarrow \frac{2x+2}{4}+\frac{4x-1}{4}=5.5$

$\Rightarrow \frac{2x+2+4x-1}{4}=5.5$

$\Rightarrow 6x+1=22$

$\Rightarrow x=\frac{21}{6}=3.5$
