Question

If7y/5 = y - 4, then the value of
y = ?
​

Answer 1

7y/5=y-4

7y=(y-4)5

7y=5y-20

7y-5y= -20

2y= -20

y= -20/2

y = -10

Answer 2

Answer:

y=-10

Step-by-step explanation:

7y/5=y-4

by cross multiplication 7y=5y-20

7y-5y=-20

2y=-20

y=-10

check

7(-10)/5=-10-4

-70/5=-14

-14=-14

lhs=rhs

so y=-10
