Answer:
B.
Explanation:
We have been given a system of equations. We are asked to choose the ordered par that is the solution to the given system.
![y=-7x+2...(1)](https://img.qammunity.org/2021/formulas/mathematics/high-school/r0cs1rcobwq86njg68optfma9jxgdhgint.png)
![y=9x-14...(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/8nx1ogo8zjk412b2o0rhrzc8rijh71zj04.png)
To solve our given system, we will equate both equations as:
![9x-14=-7x+2](https://img.qammunity.org/2021/formulas/mathematics/high-school/894g03o4o8demus058rsgvmikfd1ulg6n5.png)
Combine like terms:
![9x+7x-14+14=-7x+7x+2+14](https://img.qammunity.org/2021/formulas/mathematics/high-school/nw9dv1b96xbpx6roflq87p5o1f7k50nng2.png)
![16x=16](https://img.qammunity.org/2021/formulas/mathematics/high-school/27uwhcgchoaqbero22zte25je2cls2qq7l.png)
![x=(16)/(16)=1](https://img.qammunity.org/2021/formulas/mathematics/high-school/uegfitabbbf99lccxxbud5gtfu7c4nmtj9.png)
Upon substituting
in equation (1), we will get:
![y=-7(1)+2\\\\y=-7+2\\\\y=-5](https://img.qammunity.org/2021/formulas/mathematics/high-school/d91smabyy60vqtgply73xowvyu2hu647qd.png)
Therefore, the ordered pair
is the solution of the given system and option B is the correct choice.
