Nilai x dari persamaan\frac{5+x}{6} - \frac{10-x}{3} = 1[/tex]

emimo $\frac{5+x}{6}-\frac{10-x}{3}=1$
=> $\frac{3(5+x)-6(10-x)}{18}=1$
=> $15+3x-60+6x=18$
=> $9x=18-15+60$
=> $9x=63$
=> $x=7$

Semoga membantu

IcukSugiarto $\bold{\underline{Solution:}}\\\\\boxed{ \frac{5+x}{6}- \frac{10-x}{3}=1 }\\\boxed{ \frac{5+x}{6}=1+\frac{10-x}{3} }\\\boxed{ \frac{5+x}{6}= \frac{3}{3} +\frac{10-x}{3} }\\\boxed{ \frac{5+x}{6}= \frac{3+10-x}{3} }\\\boxed{ \frac{5+x}{6}= \frac{13-x}{3} }$

$kali\ silang\ sehingga:\\\\\boxed{3(5+x)= 6(13-x) }\\\\\boxed{15+3x= 78-6x }\\\\\boxed{3x+6x= 78-15 }\\\\\boxed{9x= 63 }\\\\\boxed{x= \frac{63 }{9} }\\\\\boxed{x= 7}$
