Answer 2

Solution:

$3 ( y - 4 ) = 5 ( 2y + 1 )$

$⟹3y-12=10y+5$

Variable terms will come in left and constant terms will come in right.

$⟹3y-10y=5+12$

Also, their signs will be changed.

$⟹-7y=17$

$⟹y=-17/7$

As, (-17) is not divisible by 7, then we will take the answer either in fraction or in Decimal.

$⟹y=-2.42$
