Sonny is collecting rare gems to add to his large collection. Sonny currently has 76 gems and would like to get to 100 gems by collecting an additional 4 gems per month.

Write an equation and solve for the number of months it will take Sonny to collect 100 gems.

Let's denote the number of months it will take Sonny to collect enough gems as \( x \).

Currently, Sonny has 76 gems and collects 4 gems per month. Therefore, the total number of gems Sonny will have after \( x \) months can be expressed as:

\[ 76 + 4x \]

Sonny wants to reach a total of 100 gems, so we can set up the equation:

\[ 76 + 4x = 100 \]

Now, we will solve for \( x \):

  1. Subtract 76 from both sides of the equation:

\[ 4x = 100 - 76 \]

\[ 4x = 24 \]

  1. Divide both sides by 4:

\[ x = \frac{24}{4} \]

\[ x = 6 \]

So, the equation is \( 76 + 4x = 100 \) and it will take Sonny 6 months to collect enough gems to reach his goal of 100 gems.
