True False, The solution to an equation is a value of the variable that makes the equation true. True False, An open circle on the number line indicates that the boundary point is included in the solution ..., Steps for Using Substitution to Determine Whether a Number in a Given Set Makes an Equation True Step 1: Substitute the value given for the variable into the equation for the variable. Step 2 ..., The value is still a solution of the new equation, but since , the value is also a solution of the new equation. However, it clearly contradicts (is not a solution of) the original equation. This gives rise to an auxiliary principle of equation solving: After solving an equation check your solutions by substituting them in the original equation.
