Question

LET x=0 x-2y=4 what is the value of y?

Solve for the missing variable: LET y=0: x-2y=4 what is the value of x?



​

Answer 1

When x = 0, then y = -2

When y = 0, then x = 4

Explanation:

We are given with the following equation;

x - 2y = 4

Now, we have to find the respective values of x and y for each value of x = 0 and y = 0.

Firstly, putting the value of x = 0;

x - 2y = 4

0 - 2y = 4

-2y = 4

y =
`(4)/(-2)` = -2

This means that when x = 0, then y = -2.

Similarly, putting the value of y = 0;

x - 2y = 4

`x-(2* 0)=4`

x - 0 = 4

x = 4

This means that when y = 0, then x = 4.
