A General Rule for Solving 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.

To solve a system of three equations in three variables, we will be using the linear combination method. This time we will take two equations at a time to eliminate one variable and using the resulting equations in two variables to eliminate a second variable and solve for the third.

Steps in Balancing a Chemical Equation Count each type of atom in reactants and products.Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.Repeat steps 1 and 2 until the equation is balanced.
