∣ 2 x - 5 ∣ = 8

x = - \frac{3}{2} or x = \frac{13}{2}

Decimal Notation

x = - 1.5, x = 6.5

Solution steps

∣ 2 x - 5 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x - 5 = - 8 or 2 x - 5 = 8

2 x - 5 = - 8 or 2 x - 5 = 8

x = - \frac{3}{2} or x = \frac{13}{2}

\frac{3 π}{8} - \frac{π}{8}

(\frac{( 0.9 \cdot 0.08 \cdot 1 0 ^{- 3} )}{( 2 \cdot 7.035 )})^{2}

2 x + 8 = 20

\frac{( k + i )}{1 + i} = 2 - i
