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

x equals 13 and one-fourth

x equals 21 and two-thirds

Answer: D. x=27

Step-by-step explanation:

y = 4

3x - 4y = 65

3x - 4 (4) = 65

3x - 16 = 65

3x = 65 + 16

3x = 81

x = 81/3

x = 27 <==

When y equals 4, x equals 27 but none of the answers given is correct.

Step-by-step explanation:

Let's solve for x in the equation 3x - 4y = 65, this way:

y = 4

3x - 4y = 65

3x - 4 (4) = 65

3x - 16 = 65

3x = 65 + 16

3x = 81

x = 81/3

x = 27

When y equals 4, x equals 27 but none of the answers given is correct.
