Question

5x³ - (6x + 1) = 19 - 2x + 5x³ 6. Розв'яжіть рiвняння.​

Answer 1

5x³ - (6x + 1) = 19 - 2x + 5x³
-6х - 1 = 19 - 2х
-6х + 2х = 19 + 1
-4х = 20
х= -5

Answer 2

$\displaystyle\bf\\5x^{3} -(6x+1)=19-2x+5x^{3} \\\\5x^{3} -6x-1=19-2x+5x^{3} \\\\5x^{3} -6x+2x-5x^{3} =19+1\\\\-4x=20\\\\\boxed{x=-5}$
