$y = - 6$ $y=-6$

$12 (5 + 2 y) = 4 y - (6 - 9 y)$ $12(5+2y)=4y-(6-9y)$

$\Rightarrow 60 + 24 y = 4 y - 6 + 9 y$ $=> 60+24y=4y-6+9y$

$\Rightarrow 60 + 24 y = 13 y - 6$ $=> 60+24y=13y-6$

$\Rightarrow 24 y - 13 y = - 60 - 6$ $=> 24y-13y=-60-6$

$\Rightarrow 11 y = - 66$ $=> 11y=-66$

$\Rightarrow y = - \frac{66}{11}$ $=> y=-66/11$

$\Rightarrow y = - 6$ $=> y=-6$

$y = - 6$ $y = -6$

$12 (5 + 2 y) = 4 y - (6 - 9 y)$ $12(5 + 2y) = 4y - (6 - 9y)$

$60 + 24 y = 4 y - 6 + 9 y$ $60 + 24y = 4y - 6 + 9y$

$60 + 24 y = 13 y - 6$ $60 + 24y = 13y - 6$

$24 y - 13 y = - 6 - 60$ $24y - 13y = - 6 - 60$

$11 y = - 66$ $11y = - 66$

$\frac{11 y}{11} = - \frac{66}{11}$ $(11y)/11 = - 66/11$

$(cancel11y)/cancel11 = - 66/11$

$y = -6$

How do you solve 12(5 + 2y) = 4y - (6 - 9y)12(5+2y)=4y−(6−9y)12(5 + 2y) = 4y - (6 - 9y)?
