Me. i will give 100 point!
1) what is the solution to the system of equations?
2x+4y=122 x + 4 y = 12
y=1/4x-3y = 1 4 x − 3
a)(0.5, 5)
b)(5, 0.5)
, 8)
d)(8, -1)

2) what is the solution to the system of equations?
y=2x-3.5y = 2 x − 3.5
x-2y=-14
a)(7, 10.5)
b)(3.5, -7)
c)(10.5, 7)
, 3.5)

2) B)

1) D)

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

[Plug this back into both equations above to get the y-coordinate of 10,5];

* 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

[Plug this back into both equations above to get the y-coordinate of −1];
