Answer:

a = -b/x

Explanation:

Solve this the way you solve any equation: undo the operations done to the variable, in reverse order.

Here, the variable (a) is multiplied by x, then b is added to the sum. So, first we undo the addition by subtracting b from the equation:

ax = -b

Now, we undo the multiplication by dividing the equation by x:

a = -b/x
