Question

what is the value of x in the equation 3x-4y=65 when y=4?

Answer 1

Step-by-step explanation:

$3x - 4(4) = 65 \\ 3x - 16 = 65 \\ 3x = 65 + 16 \\ 3x = 81 \\ \\ x = \frac{81}{3} \\ \\ x = 27$

Answer 2

Step-by-step explanation:

3x – 4y = 65

3x – 4(4) = 65

3x - 16 = 65

3x = 81

 x = 27

Answer:

x = 27 when y = 4
