That depends on the specific equation. The general idea is to "isolate" the variable, for example "x", manipulating the equation in such a way that all terms that contain "x" are on the left, and all terms that don't contain it, are on the right.

40 + X = 25 subtract 40 from each side
The first step is to include an equality sign in it otherwise it is not an equation. If you mean: 4x = 1-11 then 4x = -10 and x = -10/4 So then: x = -2.5
Defining the problem.
The first step in solving an equation with a variable is doing the inverse operation. For example:4x + 8=32The first step would be to subtract 8 from 32. Since the operation is addition you would do the inverse which is subtraction. Then you would go on to divide 24 by 4Because 32-8= 24 Then you would get an answer of x=6 This answer is correct because 6 multiplied by 4 is 24
The first step, in solving a quadratic equation in a variable x using this method, is to complete the square defined by the terms in x2 and x, by adding and subtracting a suitable constant.
