Question 1158250: The following is a system of two linear equations in two variables.

x + y = 7
2x + 2y = 14
The graph of the first equation is the same as the graph of the second equation, so the system has . We express these solutions by writing
x = t
y =

where t is any real number. Some of the solutions of this system are
3,

,
−2,

, and
7,

.

Make a data table. Pick some x values and find the corresponding y values of each.
x%2By=7
y%2Bx=7
y=-x%2B7
