2y-z/x for x=-3, y-13, and z=5

24.333

How did you get that?

To find the value of 2y - z/x for the given values of x, y, and z, you need to substitute these values into the expression and perform the necessary calculations.

Given:
x = -3
y = 13
z = 5

Let's substitute these values into the expression:

2y - z/x = 2(13) - 5/(-3)

Now, simplify the expression:

2y - z/x = 26 + 5/3

To add the whole number (26) with a fraction (5/3), we need to find a common denominator. The denominator of the fraction is already 3, so we can rewrite 26 as a fraction with a denominator of 3:

26 = 26/1 (in fraction form)

The common denominator is 3, so we need to convert 26 into a fraction with a denominator of 3:

26/1 = (26 * 3) / (1 * 3) = 78/3

Now, add the fractions:

78/3 + 5/3 = (78 + 5)/3 = 83/3

Therefore, 2y - z/x, when x = -3, y = 13, and z = 5, is equal to 83/3.
