Guess the form of the solution. The key idea is to replace the dependent variable or independent variable by a new variable that is expressed in terms of both of them. The last step is to again use substitution, in this case we know that x = 1, but in order to find the y value of the solution, we just substitute x = 1 into either equation.

First, it requires the graph to be perfectly drawn, if the lines are not straight we may arrive at the wrong answer.
