Question

What is ax-b=c for x

Answer 1

Do the order of operations backwards. so SAMDEB
subtraction --> -b
add b to both sides.
so now it's ax= c+b
there is no addition
multiplication --> (A)x(X), divide by A
Now it's x= (c+b)/a

Answer 2

Isolate x ( leave x alone )

So you first subtract b and put it to the other side.

ax = c-b

Then divide both sides by a.

x = c-b / a
