Answer 2

ANSWER :-

• The value of y is 7/4

TO FIND :-

• The value of y.

SOLUTION :-

$\implies \bf \: \dfrac{ - 15(2 - y) - 5(y + 6)}{1 - 3y} = 10 \\ \\ \implies \bf \: \dfrac{ - 30 + 15y -5y - 30 }{1 - 3y} = 10 \\ \\ \implies \bf \: \dfrac{ - 30 - 30 + 15y - 5y}{1 - 3y} = 10 \\ \\ \implies \bf \: \dfrac{ - 60 + 10y}{1 - 3y} = 10$

By cross multiplication

$\implies \bf \bold \: - 60 + 10y = 10(1 - 3y) \\ \\ \implies \bf \bold \: - 60 + 10y = 10 - 30y \\ \\ \implies \bf \bold \:10y + 30y = 10 + 60 \\ \\ \implies \bf \bold \:40y = 70 \\ \\ \implies \bf y = \dfrac{70}{40} \\ \\ \implies \bf \: y \: = \dfrac{7}{4}$

Hence the value of y is 7/4
