Question

Find the value of y in the equation 2/5x - y = 10 when x = 60.

A) 20
B) 10
C) 30
D) 40

Answer 1

The value of y in the equation ⅓x - y = 10 when x = 60 is found to be 14 after substituting x with 60 and performing the arithmetic. This value is not in the given options, suggesting a potential error in the question or options.

Step-by-step explanation:

To find the value of y in the equation ⅓x - y = 10 when x = 60, we first substitute 60 for x:

⅓(60) - y = 10

Calculate ⅓ of 60:

2/5 × 60 = 24

Now the equation is:

24 - y = 10

To solve for y, we subtract 24 from both sides of the equation:

- y = 10 - 24

- y = -14

We multiply both sides by -1 to get y by itself:

y = 14

Therefore, the value of y is 14, which is not listed in the multiple-choice options provided, indicating there may be an error in the question or options given.1
