Solving Multi Step Equations

A multi-step equation is an equation that requires more than one step to solve, often involving operations such as addition, subtraction, multiplication, and division.

Combine like terms on the right side of the equation.

To isolate a variable, perform inverse operations to move all terms involving the variable to one side of the equation and constant terms to the other side.

Combining like terms involves adding or subtracting terms that have the same variable raised to the same power.

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by each term inside a set of parentheses.

Combine like terms to get 7a + 9 = 2, then isolate 'a' by subtracting 9 from both sides and dividing by 7.

The solution is n = -5.

Distribute -4 to both 'a' and -5.

Substitute the solution back into the original equation to see if both sides are equal.

Maintaining balance means that whatever operation you perform on one side of the equation must also be performed on the other side to keep the equation true.
