Steps to Solve Linear Equations

The following steps will help you solve linear equations.

  1. Expand any brackets in the equation
  2. Gather terms with variables to left side of the equal sign, and numbers to right side of the equal sign.
  3. Combine the like terms
  4. Divide across to isolate the variable.


Solve the equation below for \(x\). \[2(3-x)+4x-1=4-2(x+1)-3 \]

Let's see these steps in action.

Step 1: Expand the brackets.


Step 2: Gather terms:.


Step 3: Combine like terms.

\[4x = -7\]

Step 4: Divide across to isolate the variable.

\[x = {-7 \over 4}\]
