how do i get the second equation into standard form. A+B=C?

[tex]\boxed{9x+2y=-16}[/tex]
The standard form of the equation of a line is given by:
[tex]Ax+By=C \\ \\ A>0[/tex]
To get the second equation into standard form let's follows these steps:
Step 1. Multiply both sides by 2:
[tex]y=\frac{-9x-16}{2} \\ \\ 2y=2\left(\frac{-9x-16}{2}\right) \\ \\ 2y=-9x-16[/tex]
Step 2. Add 9x to both sides:
[tex]2y=-9x-16 \\ \\ 2y+9x=-9x-16 \\ \\ 9x+2y=-16[/tex]
Finally, this equation in standard form is:
[tex]\boxed{9x+2y=-16}[/tex]
