==> ac = d - b

==> a = (d - b)/c

Your ans will be option no. 1)

Start by getting “ac” by itself. You do this by subtracting b from both sides, since it’s currently added on the left.

ac = d-b

Get a by itself by dividing by c, since c currently multiplied by a.

a = (d-b)/c

The first answer is correct.
