Answer:
Step-by-step explanation:
1. x - 1 = [tex]\frac{-1}{2}[/tex]
x = [tex]\frac{-1}{2}[/tex] +1
x = [tex]\frac{1}{2}[/tex]
2. 8x - 5 =9
8x = 9 - 5
8x = 4
x = [tex]\frac{4}{8} = \frac{1}{2}[/tex]
3. 2[tex]x^{3}[/tex] = [tex]\frac{1}{4}[/tex]
[tex]x^{3}[/tex] = [tex]\frac{1}{4}[/tex] x [tex]\frac{1}{2}[/tex]
[tex]x^{3}[/tex] = [tex]\frac{1}{8}[/tex]
x = [tex]\sqrt[3]{\frac{1}{8} }[/tex]
x = [tex]\frac{1}{2}[/tex]
