|r-8|=5

Lösung

∣ r - 8 ∣ = 5

r = 3 or r = 13

Schritte zur Lösung

∣ r - 8 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

r - 8 = - 5 or r - 8 = 5

r - 8 = - 5 or r - 8 = 5

r = 3 or r = 13

s im pl i f y \frac{x ^{6}}{x ^{- 4}}

∣ x - 2 ∣ > 1

2 (x + 5) = 6 x + 4

\frac{2 x - 7}{3} = 5

87.1 = \frac{[ ( 1.96 + x ) 10 ] ^{2}}{( 15 - 12 ) ^{2}}
