Question

Hello I got this wrong will you help me solve

Answer 1

Solve for y

`4x+3y=-21`

Subtract 4x both sides

`\begin{gathered} 4x+3y-4x=-21-4x \\ 3y=-21-4x \\ \end{gathered}`

Divide by 3 into both sides

`\begin{gathered} (3y)/(3)=-(21)/(3)-(4x)/(3) \\ y=-7-(4)/(3)x \\ by\text{ reordering} \\ y=-(4)/(3)x-7 \end{gathered}`

Answer:

`y=-(4)/(3)x-7`
