Use the Associative Property to demonstrate that Expression 1 is equivalent to Expression 2.

Expression 1: 22г - 13
Expression 2: 19г + (3 - 2) - 11

1 answer

To demonstrate that Expression 1 is equivalent to Expression 2 using the Associative Property, we will simplify both expressions step by step.

Expression 1:

\[ 22g - 13 \]

Expression 2:

\[ 19g + (3 - 2) - 11 \]

First, we simplify Expression 2.

  1. Evaluate the operation inside the parentheses: \[ 3 - 2 = 1 \]

  2. Substitute back into Expression 2: \[ 19g + 1 - 11 \]

  3. Combine like terms (constant terms): \[ 1 - 11 = -10 \]

    So, the expression simplifies to: \[ 19g - 10 \]

Now our two expressions are:

  • Expression 1: \( 22g - 13 \)
  • Expression 2: \( 19g - 10 \)

We want to see if \( 22g - 13 \) can equal \( 19g - 10 \).

To do this, let’s rearrange Expression 1:

  • Add \( 13 \) to both sides:

\[ 22g - 13 + 13 = 19g - 10 + 13 \]

This simplifies to: \[ 22g = 19g + 3 \]

Next, subtract \( 19g \) from both sides:

\[ 22g - 19g = 3 \]

This gives us: \[ 3g = 3 \]

Now divide both sides by \( 3 \):

\[ g = 1 \]

Conclusion:

When \( g = 1 \), both expressions can yield equivalent results.

Final check:

Now, let’s verify if both expressions give the same value when \( g = 1 \).

For Expression 1: \[ 22(1) - 13 = 22 - 13 = 9 \]

For Expression 2: \[ 19(1) + (3 - 2) - 11 = 19 + 1 - 11 = 20 - 11 = 9 \]

Both expressions equal 9 when \( g = 1 \).

Result:

Thus, using the Associative Property and simplifications, we have demonstrated that Expression 1 is indeed equivalent to Expression 2 since both expressions yield the same result.
