10|7x+3|=0

10 ∣ 7 x + 3 ∣ = 0

x = - \frac{3}{7}

Decimal Notation

x = - 0.42857 \dots

Solution steps

10 ∣ 7 x + 3 ∣ = 0

Divide both sides by

10

∣ 7 x + 3 ∣ = 0

Apply absolute rule: If

∣ u ∣ = 0

then

u = 0

7 x + 3 = 0

7 x + 3 = 0 : x = - \frac{3}{7}

x = - \frac{3}{7}

x^{2} - 10 x + 41 > 0

x^{2} - 2 x + 1 = 9

1.2 X + 2.5 \leq 20

\frac{( x + h ) ^{2} + 7 ( x + h ) - ( x ^{2} + 7 x )}{h}

x - 2 x^{2} + 1 \geq 0
