|2x|=|x+3|

∣ 2 x ∣ = ∣ x + 3 ∣

x = - 1 or x = 3

Solution steps

∣ 2 x ∣ = ∣ x + 3 ∣

Find positive and negative intervals

x < - 3, - 3 \leq x < 0, x \geq 0

Solve the inequality for each interval

No Solution or x = - 1 or x = 3

x = - 1 or x = 3

\frac{2 x ^{3} y ^{7}}{4 x ^{3} y ^{3}}

\frac{3}{1000} (x - 100)^{2} + 10 = 30

1 0^{2} + x^{2} = 1 2^{2}

- 2 w > - 2 or 4 w - 2 > 14

x - 10 = 0
