Solve for x.

–2<5x+3<13
Write your answer as a compound inequality with integers.

1 answer

To solve the compound inequality \(-2 < 5x + 3 < 13\), you can break it into two separate inequalities:

  1. \(-2 < 5x + 3\)
  2. \(5x + 3 < 13\)

Step 1: Solve the first inequality

  1. \(-2 < 5x + 3\)

Subtract 3 from both sides:

\[ -2 - 3 < 5x \]

\[ -5 < 5x \]

Now, divide both sides by 5:

\[ -1 < x \]

So, this simplifies to:

\[ x > -1 \]

Step 2: Solve the second inequality

  1. \(5x + 3 < 13\)

Subtract 3 from both sides:

\[ 5x < 13 - 3 \]

\[ 5x < 10 \]

Now, divide both sides by 5:

\[ x < 2 \]

Step 3: Combine the results

Now we have two inequalities:

  1. \(x > -1\)
  2. \(x < 2\)

Putting this together, we can express the solution as a compound inequality:

\[ -1 < x < 2 \]

Final Answer

The solution for \(x\) in the form of a compound inequality is:

\[ (-1, 2) \]

If you want to express this in terms of integers, the integers that satisfy this inequality are:

\[ 0, 1 \]

So, the integer solution can also be written as:

\[ x \in {0, 1} \]
