Ответ:
х = 1
Объяснение:
[tex](2x + 6)(5x - 3) = x(6 + 10x)[/tex]
[tex]10 {x}^{2} - 6x + 30x - 18 = 6x + 10 {x}^{2} [/tex]
[tex]10 {x}^{2} + 24x - 18 = 6x + 10 {x}^{2} [/tex]
[tex]10 {x}^{2} + 24x - 6x - 10 {x}^{2} = 18[/tex]
сокращаем 10х² и -10х²
[tex]18x = 18[/tex]
[tex]x = \frac{18}{18} [/tex]
[tex]x = 1[/tex]
(2x+6)(5x-3)=x(6+10x)
10x²-6x+30x-18=6x+10x²
24x=6x+18
24x-6x=18
18x=18
x=18:18
x=1

Verified answer
Объяснение:
(2x+6)(5x-3)=x(6+10x)
10x²-6x+30x-18=6x+10x²
24x=6x+18
24x-6x=18
18x=18
x=18:18
x=1
