Question

If $\frac{3}{4}x+8=17$, then the value of $x$ is ________ .

• A. $-12$
• B. $36$
• C. $12$
• D. $-36$

Answer 1

The correct option is C $12$

$\Rightarrow$ $\frac{3}{4}x+8=17$

$\Rightarrow$ $\frac{3}{4}x=17-8$

$\Rightarrow$ $\frac{3}{4}x=9$

$\Rightarrow$ $x=9\times \frac{4}{3}$

$\Rightarrow$ $x=3\times 4$

$\therefore$ $x=12$

$\therefore$ $\frac{3}{4}x+8=17$, then the value $x$ is $12$.
