Answer:

${\huge{\pink{\underline{\underline{Question}}}}}$

Solve and check your answer 3x-1/5-x/7=3

${\huge{\pink{\underline{\underline{Solution}}}}}$

According to question,

$\frac{3x-1}{5}-\frac{x}{7}=3$

$=>\frac{7(3x-1)}{35}-\frac{5x}{35}=7$

$=>\frac{21x-7-5x}{35}=3$

$=>16x-7=3×35$

$=>16x=105+7$

$=>x=\frac{112}{16}$

x=7..

${\huge{\pink{\underline{\underline{Check}}}}}$

Put the value of x in the equation and solve;

$\frac{(3×7)-1}{5}-\frac{7}{7}$

$=>\frac{21-1}{5}-\frac{1}{1}$

$=>\frac{20}{5}-1$

$=>4-1$

$=>3$
