Question

e) (X - 5)/10 + (1 - 2x)/5 = (3-X)/4​

Answer 1

$\frac{x-5}{10}+\frac{1-2x}{5}=\frac{3-x}{4}$

$\frac{x-5}{10}+\frac{2-4x}{10}=\frac{3-x}{4}$

$\frac{x-5+2-4x}{10}=\frac{3-x}{4}$

$\frac{-3-3x}{10}=\frac{3-x}{4}$

$4(-3-3x)=10(3-x)$

$-12-12x=30-10x$

$-12x+10x=30+12$

$-2x=42$

$2x=-42$

$x=-\frac{42}{2}$

$x=-21$
