Question:
Solve each of the following equation and also check your result in each case:
$x-\frac{(x-1)}{2}=1-\frac{(x-2)}{3}$
Solution:
$x-\frac{(x-1)}{2}=1-\frac{(x-2)}{3}$
or $\frac{2 \mathrm{x}-\mathrm{x}+1}{2}=\frac{3-\mathrm{x}+2}{3}$
or $\frac{\mathrm{x}+1}{2}=\frac{5-\mathrm{x}}{3}$
or $3 \mathrm{x}+3=10-2 \mathrm{x}$
or $5 \mathrm{x}=10-3$
or $\mathrm{x}=\frac{7}{5}$
Check :
L. H.S. $=\frac{7}{5}-\frac{\frac{7}{5}-1}{2}=\frac{7}{5}-\frac{1}{5}=\frac{6}{5}$
R.H.S. $=1-\frac{\frac{7}{5}-2}{3}=1-\frac{-3}{15}=\frac{6}{5}$
$\therefore$ L.H.S. $=$ R.H.S. for $x=\frac{7}{5}$
