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

Question

x equals 13 and one-fourth
x equals 21 and two-thirds

Answer 1

To find the value of x when y equals 4 in the equation 3x - 4y = 65, we substitute y = 4 into the equation:

3x - 4(4) = 65
3x - 16 = 65
3x = 65 + 16
3x = 81
x = 81/3
x = 27

Therefore, x equals 27 when y equals 4. So the correct answer is not listed.
