Solve the following linear equation:

$m minus fraction numerator m minus 1 over denominator 2 end fraction equals 1 minus fraction numerator m minus 2 over denominator 3 end fraction$

straight m minus fraction numerator straight m minus 1 over denominator 2 end fraction equals 1 minus fraction numerator straight m minus 2 over denominator 3 end fraction

Since, LCM of 2 and 3 is 6.

∴ Multiplying both sides by 6, we have

 6 $cross times$ m - 6 $cross times$ $fraction numerator space space straight m minus 1 over denominator 3 end fraction space equals space 6 cross times 1 minus 6 cross times fraction numerator straight m minus 2 over denominator 3 end fraction$

or 6m -3(m-1) = 6 - 2(m-2)

or 6m - 3m + 3 = 6 -2m + 4

or (6-3)m + 3 = (6+4) - 2m

or 3m + 3 = 10 - 2m

Transposing 3 to RHS and -2m to LHS, we have

 3m + 2m = 10 - 3

or 5m =7

or $straight m equals 7 over 5$ (Dividing both sides by 5)

Check: LHS = $straight m minus fraction numerator straight m minus 1 over denominator 2 end fraction$

 = $7 over 5 minus fraction numerator begin display style 7 over 5 end style minus 1 over denominator 2 end fraction equals 7 over 5 minus fraction numerator begin display style 2 over 5 end style over denominator 2 end fraction$

 = $7 over 5 minus 2 over 5 cross times 1 half$

 RHS = $1 minus fraction numerator straight m minus 2 over denominator 3 end fraction$
