Помогите пожалуйста прошу

Answer 1

$2(x - 1) + 3(2 - 1.5x) = 5(2 - x) \ 2x - 2 + 6 - 4.5x = 10 - 5x \ - 2.5x + 4 = 10 - 5x \ - 2.5x + 5x = 10 - 4 \ 2.5x = 6 \ x = 6 div 2.5 = 6 div frac{25}{10} = 6 times frac{10}{25} = 6 times frac{2}{5} = frac{12}{5} = 2.4$
Ответ: 2,4.

Answer 2

2(x-1)+3(2-1.5x)=5(2-x)

2x-2+6-4.5x=10-5x

-2.5x+4=10-5x

-2.5x+5x=10-4

2.5x=6

x=2.4
