Question

What is the solution to the system of equations?

Answer 1

Answer:

B. $(7, 10,5)$

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

$x = 7$ [Plug this back into both equations above to get the y-coordinate of 10,5]; $10\frac{1}{2} = y$

* 10½ = 10,5
