Question

7y+3/2-5y=6/7 solve and verify it.​

Answer 1

Step-by-step explanation:

7y+3/2-5y=6/7

2y=6/7-3/2

2y= -9/14

y= -9/28

for verification:

when y= -9/28 then,

7*(-9/28)+3/2-5*(-9/28)

=6/7

LHS= RHS verified

Answer 2

Answer:

$7y+\frac{3}{2}-5y=\frac{6}{7} \\7y-5y=\frac{6}{7}-\frac{3}{2} \\\\2y=\frac{12-21}{14} \\y=\frac{-9}{14\times2}\\\\y=\frac{-9}{28}\\Proof:\\L. H.S.\\=7\times\frac{-9}{28}+\frac{3}{2}-5\times\frac{-9}{28} \\\\=\frac{-63}{28}+\frac{42}{28} +\frac{45}{28} \\\\ =\frac{-63+42+45}{28}\\=\frac{24}{28}\\=\frac{6}{7}\\=R.H.S.$
