solve one-variable linear equations of increasing complexity with natural number solutions; verify equation solutions by substitution
Elaborations
recognising that solving an equation is a process of determining a value that makes the equation true; and using substitution to determine whether a given number is a solution to an equation or not
solving equations using concrete materials, the balance model and backtracking, explaining the process
