Answer :

To find an expression that represents the difference when [tex]\(2x - 6\)[/tex] is subtracted from [tex]\(7x - 0.5\)[/tex], follow these steps:

1. Set up the expression for the difference:

We are given two expressions: [tex]\(7x - 0.5\)[/tex] and [tex]\(2x - 6\)[/tex]:
[tex]\[ (7x - 0.5) - (2x - 6) \][/tex]

2. Distribute the negative sign across the second expression:

When subtracting [tex]\(2x - 6\)[/tex], distribute the negative sign:
[tex]\[ (7x - 0.5) - 2x + 6 \][/tex]

3. Combine like terms:

Combine the terms containing [tex]\(x\)[/tex] and the constant terms separately:

- Combine the [tex]\(x\)[/tex] terms:
[tex]\[ 7x - 2x = 5x \][/tex]

- Combine the constant terms:
[tex]\[ -0.5 + 6 = 5.5 \][/tex]

4. Write the simplified expression:

Therefore, the simplified expression that represents the difference is:
[tex]\[ 5x + 5.5 \][/tex]

Thus, the expression which represents the difference when [tex]\(2x - 6\)[/tex] is subtracted from [tex]\(7x - 0.5\)[/tex] in simplest terms is:
[tex]\[ 5x + 5.5 \][/tex]
