Yes, the statement is correct. Both elimination and substitution are methods used to solve linear equations, but depending on the specific equation, one method may be easier or more efficient than the other. Substitution is often considered easier when one variable is already isolated because it involves substituting the expression for that variable directly into the other equation.
