Question

(vii) 15(y - 4) - 2(y - 9) +504 + 6) = 0​

Answer 1

Step-by-step explanation:

15(y-4)-2(y-9)+504+6=0

(15y-60)-(2y-18)+504+6=0

**********************+ 510=0

*********************= 0-510= -510

15y-60-2y-18 = -510

17y (by adding 15y and 2y) - 78 ( by adding 60 and 18)= -510

17y-78= -510

17y= -510+78

17y=- 432

y= -432/17
