What is the value of x in the equation 3 x minus 4 y equals 65, when y equals 4?

x = 27

Step-by-step explanation:

Given

3x - 4y = 65 ← substitute y = 4 into the equation

3x - 4(4) = 65

3x - 16 = 65 (add 16 to both sides )

3x = 81 ( divide both sides by 3 )

x = 27

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.
