Question

Malik’s solution to the equation ,2/5x-4y=10 when x=60, is shown below.what error did Malik make first when solving the equation ?

Answer 1

Answer:

y = 7/2  

Step-by-step explanation:

We are given that

(2/5)x - 4y = 10

When

x = 60

then

(2/5)60 - 4y = 10

2(12) - 4y = 10

24 - 4y = 10

- 4y = 10 - 24

-4y = -14

  y = -14/-4 = 7/2

Thus

When

x = 60 then

y = 7/2

Note:

As the question is not completed so now you have to compare this solution with your original question and then find out the mistake.I hope it helpful and you can also talk about this is chat with me for more details.
