Question

What is the solution to the linear system? y = -x + 7 -2x + 2y = 6 A.(-2,9) B. (2, 5) C. (2. 9) D. (No solution)

Answer 1

$\begin{gathered} -2x+2(-x+7)=6 \\ -2x-2x+14=6 \\ -4x=6-14 \\ -4x=-8 \\ x=2 \\ \\ y=-(2)+7 \\ y=-2+7 \\ y=5 \\ \\ (2,5)\text{ This would be the solution} \end{gathered}$
