4a.4²x +3=1

Slotuion:

4²x + 3=1 : <em>x</em>= -⅛ (Decimal:<em>x</em>= -0.125)

Steps

4² x +3=1

4²=16

16x + 3=1

Subract 3 from borh sides

16x +3-3=1-3

Simplify

16x=-2

Divides both sides by 16

\frac{16 \times }{16} = [tex] \frac{ - 2}{16}

[/tex]

Simplitfy

\frac{16 \times }{16} :  x

Simplify

\frac{ - 2}{16}: -⅛

<em>x</em> = -⅛

therefore the answer is <em>x</em><em>=</em><em> </em><em>-</em><em>⅛</em>
