HEY
HERE IS YOUR ANSWER
_____________________________

Solution -

$5y - 2(y - 3(y - 5)) = 6 \\ 5y - 2(y - 3y + 15) = 6 \\ 5y - 2( - 2y + 15) = 6 \\ 5y + 4y - 30 = 6 \\ 9y = 6 + 30 \\ y = \frac{36}{9} \\ y = 4 \\ \\ \\ 0.3(6 - x) = 0.4(x + 4) \\ 1.8 - 0.3 x= 0.4x + 1.6 \\ 1.8 - 1.6 = 0.4x + 0.3x \\ 0.2 = 0.7x \\ 0.7x = 0.2 \\ x = \frac{0.2}{0.7} \\ x = \frac{2}{7} \\ x = 0.28$
