In this case, we'll have to carry out several steps to find the solution.
Step 01:
4x+5y=12
y = ?
Step 02:
4x + 5y = 12
5y = 12 - 4x
[tex]\begin{gathered} y\text{ = }\frac{12}{5}\text{ - }\frac{4x}{5} \\ y\text{ = }\frac{-4}{5}x\text{ + }\frac{12}{5} \end{gathered}[/tex]The answer is:
y = -4/5 x + 12/5
