QuestionIdentify the equation pair that cannot be solved as a system: 1) $2x + 3y = 4$ and $y = 4 - x$ 2) $z = 3y + 4$ and $z = -y$ 3) $z = 3x - 2$ and $y = 2z - 3$.

Studdy Solution
Finally, let's analyze the third system of equations $z=3 x-2$ and $y=2 z-3$.
This system has two equations but three variables ($z$, $x$, and $y$). Therefore, this system of equations is not solvable because there are more variables than there are equations.
So, the system of equations that is not solvable is $z=3 x-2$ and $y=2 z-3$.
