The following steps provide a good method to use when solving linear equations.
- Simplify each side of the equation by removing parentheses and combining like terms.
- Use addition or subtraction to isolate the variable term on one side of the equation.
- Use multiplication or division to solve for the variable.

What are the 4 steps to solving an equation?
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.
What are the 4 steps to solving 2 step equations?
1) First, add or subtract both sides of the linear equation by the same number. 2) Secondly, multiply or divide both sides of the linear equation by the same number. 3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.
What’s the first step to solving an equation?
After simplifying, the first step in solving an equation with a variable on both sides is to get the variable on one side. This is done by reversing the addition or subtraction of one of the terms with the variable.
What are the rules for equations?
Maths – Rules when working of equations
| rule | name |
|---|---|
| 0 + x = x | identity operator – additive (left) |
| x * 1 = x | identity operator – multiplicative (right) |
| 1 * x = x | identity operator – multiplicative (left) |
| if z = x + y then x = z – y | subtracting is the inverse of adding |
What is a 2 step equation example?
Equations that can be solved in exactly two steps and gives the final value of the variable in two steps are called two step equations and are algebraic equations. Generally, two step equations are of the form ax + b = c, where a, b, c are real numbers. A few examples of two step equations are: 2x + 3 = 7.
