Question

y
$\frac{y - 4}{3} + 3y = 4$

Answer 1

$<b><font face=Copper black size=4 colour=purple>$$<b><marquee direction = "up" > <h3>$Given :

( y - 4 ) / 3 + 3y = 4

( y - 4 + 9y ) / 3 = 4

10y - 4 = 12

10y = 16

y = 16 / 10

y = 8 / 5

y = 1.6

Answer 2

$\frac{y - 4}{3} + 3y = 4 \\ \frac{y - 4 + 9y}{3} = 4 \\ y - 4 + 9y = 4 \times 3 \\ 10y - 4 = 12 \\ 10y = 12 + 4 = 16 \\ y = 16 \div 10 = 1.6$
