The first step that justifies Anne's first step while solving the expression is the commutative law of addition.

Given the equation solved by Anne's expressed as;

[tex]7x^2+(8x^2+1)[/tex]

To get the first step, we will use the commutative property of Addition as shown:

[tex]7x^2+(8x^2+1)\\= 7x^2+8x^2+1\\=8x^2+7x^2+1\\= 15x^2 + 1[/tex]

Hence the first step in the justification is the commutative law of addition.
