9.58 = 9 58/100 = 9 29/50
(2^-1)^2/2×2^0
2^(-1×2)/2^1
2^-2/2^1
2^(-2-1)
2^(-3)
(1/2)^3
Properties used (m^n)^a = m^na
(m)^-n = (1/m)^n
m^0 = 1
m^n/m^a = m^(n-a)

3(2x - 1) - 10 = 8 + 5x
6x - 3 - 10 = 8 + 5x // Apply distributive property
6x - 13 = 8 + 5x // Combine like terms
x - 13 = 8 // Take away 5x from both sides
x = 21 // Add 13 to both sides
--------------------------------
Answer: x = 21
