Question

Pls....solve this equation...pls....I am begging u....plssssss

Answer 1

Answer:

y = 3

Step-by-step explanation:

Answer 2

Answer:

I)Trial and error method required.

Let value of y be 0 ,

Then the Equation will become

10×0 - 20 = -20

Let value of y be 10 ,

Then the Equation will become

10×10 - 20 = 80

Let value of y be 5 ,

Then the Equation will become

10×5 - 20 = 30

Let value of y be 7 ,

Then the Equation will become

10×7 - 20 = 50

Let value of y be 100,

Then the Equation will become

10×100 - 20 = 980

Therefore we can see that the value of expression changes according to the the value of y.

Hence verified .

ii)Yes, from the solutions of we obtain, we can see the solution of the equation 10y-20 = 50.

That is y=7.

Hope this helps you...
