Those equations that can be solved using only two steps are known as two-step equations. As compared to one-step equations, these equations are just a little more tricky. While solving these equations, operation needs to be performed on both the left-hand side and the right-hand side of the equation. The variable portion of the equation is normally set aside and isolated to find out the value of the variable while solving two-step equations.

Teaching to Solve Two-step Equations Easily

Either perform addition or subtraction to isolate the variable portion of the equation.

Use division or multiplication to find out the value of the variable of the equation.

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 + 10 = 5.

Solution:

Step 1: Subtract 6 from both the sides of the equation.

35x + 10 - 10 = 5 - 10

=> 35x = -5

Step 2: Divide -5 with 35 to get the desired value.

x = -5/35 = -1/7
