Question

Malik's solution to the equation , when , is shown below. What error did Malik make first when solving the equation ? Malik did not multiply correctly. Malik added 240 to each side of the equation. Malik did not multiply correctly. Malik substituted 60 for y instead of x.

Answer 1

Answer:

Malik substituted 60 for y instead of x.

Step-by-step explanation:

Answer 2

Answer:

Malik substituted 60 for y instead of x.

Step-by-step explanation:

According to the given situation the computation of error that Malik make first when solving the equation is shown below:-

First, we will find the value of x

$\frac{2}{5} x - 4(60) = 10$

$\frac{2}{5} x = 10 + 240$

$\frac{2}{5} x = 250$

x = 625

Now, we have

$\frac{2}{5} x - 4 y = 10$

we will solve the above equation, to find the value of y

24 - 4y = 10

4y = 24 - 10

4y = 14

$y = \frac{14}{4}$

$y = \frac{7}{2}$

So, from the above calculation, the correct option is

Malik substituted 60 for y instead of x.
