Question

I need help with my math

Answer 1

Given

Pool of equations

Procedure

$\begin{gathered} 2y=-1x-8 \\ y=\frac{-1x-8}{2} \\ y=-\frac{1}{2}x-\frac{8}{2} \\ y=-\frac{1}{2}x-4 \end{gathered}$

$\begin{gathered} y-4=-3(x-3) \\ y-4=-3x+9 \\ y=-3x+9+4\rbrack \\ y=-3x+13 \end{gathered}$

$\begin{gathered} 0.2x+0.3y=0.5 \\ 0.3y=0.5-0.2x \\ y=\frac{-0.2x+0.5}{0.3} \\ y=-\frac{0.2x}{0.3}+\frac{0.5}{0.3} \\ y=-\frac{2}{3}x+\frac{5}{3} \end{gathered}$

$\begin{gathered} \frac{1}{4}y+3=-5x \\ \frac{1}{4}y=-5x-3 \\ y=4(-5x-3) \\ y=-20x-12 \end{gathered}$
