Question

please ans. this ques. ​

Answer 1

Step-by-step explanation:

a) by simplification

$\frac{3}{4} (7y - 1) - (2y - ( \frac{1 - y}{2} ) = y + \frac{3}{2}$

$\frac{21y}{4} - \frac{3}{4} - \frac{4y - 1 + y}{2} = \frac{2y + 3}{2}$

$\frac{21y - 3 - 8y - 2 + 2y}{4} = \frac{2y + 3}{2}$

$\frac{16y - 5}{4} = \frac{2y + 3}{2}$

By cross multiplication

$2(16y - 5) = 4(2y + 3)$

$32y - 10 = 8y + 12$

$32y - 8y = 12 + 10$

$24y = 22$

so

$y = \frac{22}{24}$

$y = \frac{11}{12}$

b)

$3y + 2 = 4(7y + 3)$

$3y + 2 = 28y + 12$

$3y - 28y = 12 - 2$

$- 25y = 10$

$y = \frac{10}{ - 25}$

$y = - \frac{2}{5}$
