Question

Y + 11 by 6 minus y + 1 by 9 is equals to Y + 7 by 4 is​

Answer 1

Answer:

$\frac{y + 11}{6} - \frac{y + 1}{9} = \frac{y + 7}{4} \\ \frac{6(y + 11)}{6 \times 6} - \frac{4(y + 1)}{9 \times 4} = \frac{9(y + 7)}{4 \times 9} \\ \frac{6y + 66}{36} - \frac{4y + 4}{36} = \frac{9y + 63}{36} \\ 6y + 66 - (4y + 4) = 9y + 63 \\ 6y - 4y - 9y + 66 - 4 - 63 = 0 \\ - 7y = - 1 \\ 7y = 1 \\ y = \frac{1}{7}$
