Question

13 (y_4) -3 (y-9) = 5 (y+4)​

Answer 1

Answer:

Y=9

Step-by-step explanation:

$13(y - 4) - 3(y - 9) = 5(y +4) \\ = > 13y - 52 - 3y + 27 = 5y + 20 \\ = > 13y - 3y - 5y - 52 + 27 - 20 = 0 \\ = > 5y - 45 = 0 \\ = > 5y = 45 \\ = > y = \frac{45}{5} \\ = >y = 9$

Answer 2

Answer:

$= > 13(y - 4) - 3(y - 9) = 5(y + 4) \\ \\ = > (13) \times (y) - (13) \times (9) - (3) \times y) + (3) \times (9) = (5) \times (y) + (5) \times (4) \\ \\ = > 13y - 52 - 3y + 27 = 5y + 20 \\ \\ = > 10y - 25 = 5y + 20 \\ \\ = > 10y - 5y = 20 + 25 \\ \\ = > 5y = 45 \\ \\ = > y = \frac{45}{5} \\ \\ = > y = 9$
