Solution

Here, we put different values of y in the given equation 5y+10=4y10.


When x=5,

5y+10=4y10 5(5)+10=4(5)10

3510.


When x=5,

5y+10=4y10 5(5)+10=4(5)10

1530.


When x=10,

5y+10=4y10 5(10)+10=4(10)10

6030.


When x=10,

5y+10=4y10 5(10)+10=4(10)10

4050.


When x=15,

5y+10=4y10 5(15)+10=4(15)10

8550.


When x=15,

5y+10=4y10 5(15)+10=4(15)10

6570.


When x=20,

5y+10=4y10 5(20)+10=4(20)10

11070.


When x=20,

5y+10=4y10 5(20)+10=4(20)10

90=90.

Therefore, the value of y is 20.
