Question

Find the value of y .

$i).650y + 25y + 845y = 4000$
$ii).65y + 45(2y) + 65(5y) + 35y = 5000$

​

Answer 1

Step-by-step explanation:

= 650y + 25y +845y = 4000

= 1520y = 4000

simply

y= 4000 / 1520

y= 50 / 19

65y + 90y + 325y + 35y = 5000

515y = 5000

simply

y = 5000/ 515

y= 1000/103

Answer 2

Answer:

650y+25y+844y=4000

1520y=4000

y=4000/1520650y

y=50/19

65y+45(2y)+65(5y)+35y=500

65y+90y+325y+35y =5000

515y=5000

y=5000/515

y=1000/103
