Question

Type and solve the two step inequality for each of the following solution: y < 9

Answer 1

Given the solution

`y<9`

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:

`\begin{gathered} y+3<9+3 \\ y+3<12 \end{gathered}`

Next multiply both sides of the expression a number of your choice, for example, 4

`\begin{gathered} 4(y+3)<12\cdot4 \\ 4y+3\cdot4<48 \\ 4y+12<48 \end{gathered}`

The two-step inequation is:

`4y+12<48`
