Answer:
2) B) [tex](7, 10,5)[/tex]
1) D) [tex](8, -1)[/tex]
Step-by-step explanation:
{y = 2x - 3,5
{x -2y = −14
x - 2[2x - 3,5] = −14
x - 4x + 7 = −14
−3x + 7 = −14
- 7 - 7
__________
−3x = −21
___ ___
−3 −3
[tex]x = 7[/tex] [Plug this back into both equations above to get the y-coordinate of 10,5]; [tex]10\frac{1}{2} = y[/tex]
* 10½ = 10,5
_______________________________________________
{y = ¼x - 3
{2x + 4y = 12
2x + 4[¼x - 3] = 12
2x + x - 12 = 12
3x - 12 = 12
+ 12 + 12
_________
3x = 24
__ __
3 3
[tex]x = 8[/tex] [Plug this back into both equations above to get the y-coordinate of −1]; [tex]-1 = y[/tex]
