|2x+1|=19

∣ 2 x + 1 ∣ = 19

x = - 10 or x = 9

Solution steps

∣ 2 x + 1 ∣ = 19

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 1 = - 19 or 2 x + 1 = 19

2 x + 1 = - 19 or 2 x + 1 = 19

x = - 10 or x = 9

d - 20 = 14

\frac{( - 8.3 ) ^{8}}{( - 8.3 ) ^{7}} \cdot \frac{( - 8.3 ) ^{4}}{( - 8.3 ) ^{3}}

∣ 2 x - 5 ∣ - 2 = x

j^{2} - 10 j + 24

\frac{3}{8} + \frac{1}{8}
