Given the solution
[tex]y<9[/tex]You need to determine a two-step inequality for it, this means, you need to perform two operations to de given solution, for example, add a constant to both sides of the expression:
[tex]\begin{gathered} y+3<9+3 \\ y+3<12 \end{gathered}[/tex]Next multiply both sides of the expression a number of your choice, for example, 4
[tex]\begin{gathered} 4(y+3)<12\cdot4 \\ 4y+3\cdot4<48 \\ 4y+12<48 \end{gathered}[/tex]The two-step inequation is:
[tex]4y+12<48[/tex]
