Solve these equations using any method you know 1) \( 3 n+4 n=-14 \)

Find the slope and the \( y \)-intercept of the graph of the equation. \[ 8 x+9 y=36 \] slope \( y \)-intercept \( \quad(x, y)=(\square) \)

\( 22 \quad \frac { 1 } { 4 } x - \frac { 5 } { 2 } = - 2 \)

18. \( \begin{aligned} y & =x-5 \\ y & =-2 x-5\end{aligned} \)

Risolvi le seques \( \frac{-x^{2}+7 x-12}{2 x^{2}-7 x+3} \geqslant 0 \)

\( \begin{array}{ll} & \text { Solve for } x: \\ 2.1 & (x-5)(x+3)=0 \\ 2.2 & 2^{x-1}=10-2^{x+1} \\ 2.3 & 5^{3 x-6}=125 \\ 2.4 & \frac{x^{2}-3}{2}=x\end{array} \)
