Solve Two-Step Equations Worksheet

8 problems

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
