Question

I need help with my math

Answer 1

Given

Pool of equations

Procedure

`\begin{gathered} 2y=-1x-8 \\ y=(-1x-8)/(2) \\ y=-(1)/(2)x-(8)/(2) \\ y=-(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=(-0.2x+0.5)/(0.3) \\ y=-(0.2x)/(0.3)+(0.5)/(0.3) \\ y=-(2)/(3)x+(5)/(3) \end{gathered}`

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