Solve for g.


4≤g+7≤14
Write your answer as a compound inequality with integers.

1 answer

To solve the compound inequality \(-4 \leq g + 7 \leq 14\), you can break it down into two separate inequalities:

  1. \(-4 \leq g + 7\)
  2. \(g + 7 \leq 14\)

Now, let's solve each part step by step.

For the first inequality:

\[ -4 \leq g + 7 \]

Subtract 7 from both sides:

\[ -4 - 7 \leq g \]

This simplifies to:

\[ -11 \leq g \quad \text{or} \quad g \geq -11 \]


For the second inequality:

\[ g + 7 \leq 14 \]

Subtract 7 from both sides:

\[ g \leq 14 - 7 \]

This simplifies to:

\[ g \leq 7 \]


Now, we can combine the results of both inequalities:

\[ -11 \leq g \leq 7 \]

This can also be expressed as a compound inequality:

\[ -11 \leq g \leq 7 \]

Thus, the final answer is:

\[ g \in [-11, 7] \] or written as \(-11 \leq g \leq 7\).
