Can anyone help me with this problem?

Which of the following equations describe the same line as the equation 3x+4y=5?

y=3/4x+5

5-3x-4y=0

y=3/4x+5/4

6x+8y=5

Thanks

Hi;

Choose the second one.

Subtract 3x from both sides.

Subtract 4y from both sides.

Put the 0 on the other side.

Which matches the second one.
