Question

$\frac{y}{7} + \frac{y - 4}{3} = 2$
​

Answer 1

Answer:

$\frac{y}{7} + \frac{y - 4}{3} = 2 \\ 3(y) + 7(y - 4) = 2 \\ 3y + 7y - 28 = 2 \\ 3y - 7y = 2 + 28 \\ - 4y = 30 \\ y = \frac{30}{ - 4} \\ y = 7.5$

Answer 2

${\bigstar}$ANSWER:

༄$\frac{y}{7} + \frac{y - 4}{3} = 2$

༄ $\frac{3(y) + 7(y - 4)}{(7)(3)} = 2$

༄$\frac{3y + 7y - 28}{21} = 2$

༄$\frac{21y - 28}{21} = 2$

༄$21y - 28 = 21 \times 2$

༄$21y - 28 = 42$

༄$21y = 42 - 28$

༄$21y = 14$

༄$y = \frac{14}{21}$

༄$y = \frac{2}{3}$
