Question
Verify the following:
$3+\frac{-7}{12}=\frac{-7}{12}+3$
$3+\frac{-7}{12}=\frac{-7}{12}+3$
✓
Answer
$\text{L.H.S. }=3+\frac{-7}{12}$
$=\frac{36-7}{12}$
$=\frac{29}{12}$
$\text{R.H.S. }=\frac{-7}{12}+3$
$=\frac{-7+36}{12}$
$=\frac{29}{12}$
$\text{L.H.S. }=\text{R.H.S. }$
$\therefore3+\frac{-7}{12}=\frac{-7}{12}+3$
$=\frac{36-7}{12}$
$=\frac{29}{12}$
$\text{R.H.S. }=\frac{-7}{12}+3$
$=\frac{-7+36}{12}$
$=\frac{29}{12}$
$\text{L.H.S. }=\text{R.H.S. }$
$\therefore3+\frac{-7}{12}=\frac{-7}{12}+3$
