What is the value of x in the equation 3×-4y=65, when y=4?

x = 27

Step-by-step explanation:

1. Plug in the y:

3x - 4(4) = 65

2. Simplify

3x - 16 = 65

3. Switch the sign of the 16 and move it to the other side of the equal sign.

3x = 81

4. Divide the 3 on both sides

3x/3 (cancels out)

81 / 3

x = 27

5. Plug the x value in with the y value to double check your answer.

3(27) - 4(4) = 65

81 - 16 = 65

X = 27

3x-4(4)=65

3x-16=65

+16 +16

3x=81

/3 /3

X =27
