Question
The following is a system of two linear equations in two variables.
x | + | y | = | 4 |
2x | + | 2y | = | 8 |
The graph of the first equation is the same as the graph of the second equation, so the system has ---Select--- one solution no solution infinitely many solutions . We express these solutions by writing
x = | t |
y = |
