What is the value of x in the equation 1 / 5 x - 2 / 3 y equals 30, when y equals 15

x=200

Step-by-step explanation: 1/5x-2/3y=30

1. Substitute y for 15: 1/5x-2/3(15)=30

2. Multiply 2/3 by 15 which is 10

3. Add 10 to 30 because of the negative sign before the -2/3

4. 1/5x=40

5. Multiply both sides by 5 to get 1x=200

6. x=200

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
