We can define two-step equations as those equations that can be solved using only two steps. As compared to one-step equations, these equations are just a little more complicated. While solving these equations, operation needs to be performed on both the left-hand side and the right-hand side of the equation. To find out the answer while solving two-step equations, normally, we put aside the variable portion of the equation on one side.

Teaching to Write and Solve Two-step Equations Easily
Either perform addition or subtraction to isolate the variable.
Once isolation of the variable is done, use division or multiplication to find out the value of the variable.
Two-step equations are of the form:
ax + b = c, where x is a variable and a, b and c are real numbers.
Here is an example of solving two-step equations easily.
Example: Solve the equation 35x + 6 = 5.
Solution:
Step 1: Subtract 6 from both the sides of the equation.
35x + 6 - 6 = 5 - 6
=> 35x = -1
Step 2: Divide -1 with 35 to get the desired value.
x = -1/35.
