Question:
Solve each of the following equation and also verify your solution:
13(y − 4) − 3(y − 9) − 5(y + 4) = 0
Solution:
$13(y-4)-3(y-9)-5(y+4)=0$
or $13 y-52-3 y+27-5 y-20=0$
or $5 y=45$
or $y=\frac{45}{5}=9$
Verification :
L.H.S. $=13(9-4)-3(9-9)-5(9+4)$
$=13 \times 5-3 \times 0-5 \times 13=0=$ R. H.S.
