Question

Using the graphing function on your calculator, find the solution to the system

of equations shown below.
3y - 9x = -6
5y - 15x = -10
O A. x=-15, y = 5
O B. x=-9, y = 3
O C. No solution
D. More than 1 solution

Answer 1

More than one solution

Explanation:

AP3X

Answer 2

It has infinite solutions.

D. More than 1 solution

Explanation:

`$\left \{ {{3y - 9x = -6} \atop {5y - 15x = -10}} \right. $`

`$\left \{ {{3y(-5) - 9x(-5) = -6(-5)} \atop {5y(3) - 15x(3) = -10(3)}} \right. $`

`$\left \{ {{-15y +45x = 30} \atop {15y - 45x = -30}} \right. $`

`0+0=0`

or

`5y = 15x - 10\\y = 3x - 2`

`3(3x-2) - 9x = -6`

`0=0`
