Answer:
The solution is (-1/2, 3 1/2), or (-0.5, 3.5)
Explanation:
Seeing that -x + 3 = y (in the second equation), substitute -x + 3 for y in the first equation, obtaining:
-x + 3 = 3x + 5
Combining the x terms, we get
3 = 4x + 5
Combining the constants, we get
4x = -2, or x = -1/2
Seeing that -x + 3 = y, substitute -1/2 for x and calculate y:
-(-1/2) + 3 = y = 3 1/2
The solution is (-1/2, 3 1/2), or (-0.5, 3.5)
