The substitution method is a systematic way to solve simultaneous linear equations by expressing one variable in terms of the other and then substituting it into the second equation.
Steps of the Substitution Method
Choose one equation and rearrange it to make one variable the subject (for example, express in terms of or vice versa).
Substitute this expression into the other equation. This reduces the system to an equation with only one variable.
Solve the resulting equation to find the value of that variable.
Substitute back the value found into the rearranged equation to find the value of the other variable.
Check the solution by substituting the values into the original equations.
