Question

solve the following equation y/4 - 1/3 = y/5+2/7​

Answer 1

Answer:

260/21 or 12.33

Step-by-step explanation:

=> y/4 - 1/3 = y/5+2/7

=> y/4-y/5 = 2/7+1/3

=> (5y-4y)/20 = (6+7)/21

=> y/20 = 13/21

=> y = 13/21×20

=> y = 260/21 or y = 12.33

Answer 2

Answer:

$\frac{y }{4} - \frac{1}{3} = \frac{y}{5} + \frac{2}{7 } \\ \frac{y}{4} - \frac{y}{5} = \frac{1}{3} + \frac{2}{7} \\ \frac{5y - 4y}{20} = \frac{7 + 6}{21} \\ (5y - 4y) \times 21 = (7 + 6) \times 20 \\ 105y - 84y =140 + 120 \\ 21y = 260 \\ y = \frac{260}{21}$
