What is the apparent solution to the system of equations?
1 answer:
Answer:
(x, y) = (-0.3, -1.6)
Step-by-step explanation:
The graph below shows these equations graphed. Their point of intersection is (-0.3, -1.6).
_____
<em>Analytical solution</em>
You can equate the expressions for y to get ...
... 12x +2 = 2x -1
... 10x = -3 . . . . subtract (2x+2)
... x = -0.3 . . . . . divide by 10
... y = 2(-.3)-1 = -1.6 . . . . use the 2nd equation to find y.
