Question

Find the solutions of the system: y = 2(5)-x and x + y = 2
0, 2)
(0, 2) and approximately (0.09, 1.91)
(0, 2) and approximately (1.91, 0.09)
no solution

Answer 1

Fill in the numbers for the original.
0=2(5)-2 <-- no
1.91=2(5)-0.09<-- no
So probably no solution. I would get a second opinion though
