Question

solve the system of equations, put answer in ordered pair form: 9x+2y=-46, -x+y=-1

Answer 1

Multiply both sides of the second equation by \(-2\) to get \(2x-2y=2\). Add this new equation to the first one, you will have \(11x=-44 \implies x=-4\). Now plug x=-4 into the second equation, and you will find that \(4+y=-1 \implies y=-5\). The answer in ordered pair form is \((-4,-5)\).

Answer 2

thank you!

Answer 3

You're welcome!

Answer 4

\[4x=2y=-36\] is the I
\[-x+y=-1\] is the II
Operating II - I:
\[-3x = -24\]
\[x=8\]
Going it in II:
\[-(8)+y=-1\]
\[y=7\]
\[A={(8;7)}\]
