Question

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

A. x equals 13 and one-fourth
B. x equals 21 and two-thirds
C. x= 23
D. x=27

Answer 1

X=27 Is the answer the rest of them are wrong.

Answer 2

x = 27

Explanation:

3x-4y = 65

Let y = 4

3x - 4*4 = 65

3x -16 = 65

Add 16 to each side

3x-16+16 = 65+16

3x = 81

Divide each side by 3

3x/3 = 81/3

x = 27
