Question

Решите уравнение
3*(2x^2-5)-2*(3x^2+x)=-3*(3x-2)

Answer 1

3(2x²-5) -2(3x²+x)= -3(3x -2)

6x² -15 -6x² -2x = -9x +6

-2x -15 = -9x +6

-2x +9x =6 +15

7x =21

x =21/7

x =3
ответ: x =3

Answer 2

3( 2х^2 - 5) - 2( 3х^2 + х ) = - 3( 3х - 2 )
6х^2 - 15 - 6х^2 - 2х = - 9х + 6
- 15 - 2х = - 9х + 6
9х - 2х = 6 + 15
7х = 21
х = 3
Ответ х = 3
