Question

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

Answer 1

Answer:

When y = 4, we can write:

3x - 4 * 4 = 65

3x - 16 = 65

3x = 81

x = 27

Answer 2

Answer:

x = 27

Step-by-step 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 by 3

3x/3 = 81/3

x = 27
