∣ - 5 x + 7 ∣ = 15

x = - \frac{8}{5} or x = \frac{22}{5}

Decimal Notation

x = - 1.6, x = 4.4

Solution steps

∣ - 5 x + 7 ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 5 x + 7 = - 15 or - 5 x + 7 = 15

- 5 x + 7 = - 15 or - 5 x + 7 = 15

x = - \frac{8}{5} or x = \frac{22}{5}

10000 \cdot (1.06)^{4} + 12000 = x \cdot \frac{( 1.06 ) ^{10} - 1}{0.06} + 2000

95 \cdot \frac{π}{180}

5 x = 5 x

2^{3} \cdot 2^{2}

x^{2} - 3 x + 2 = 0
