x^{2} + 7 x = 4 x + 28

x = - 7 or x = - 4 or x = 4

Solution steps

x^{2} + 7 x = 4 x + 28

Find positive and negative intervals

x \leq - 7, - 7 < x < 0, x \geq 0

Solve the inequality for each interval

x = - 7 or x = - 4 or x = 4

∣ - 2 x ∣ = 12

∣ z - j ∣ = 4

4 - x^{2} = x^{2} - 4

7 = ∣ - 9 u ∣ + 7

∣ 4 x ∣ = x + 1
