Question

9(4-2х)=5(3-4х)+4 Помогите решить срочно

Answer 1

9 • (4-2x) = 5 • (3-4x) + 4;

36 - 18x = 15 - 20x + 4;

36 - 18x = 19 - 20x

- 18x + 20x = 19 - 36;

2x = - 17;

x = - 8,5;

Answer 2

$9(4-2x)=5(3-4x)+4 \\ 36 - 18x = 15 - 20x + 4 \\ - 18x + 20x = 15 + 4 - 36 \\ 2x = 19 - 36 \\ 2x = -17 \\ x = -17 : 2 \\ \boxed{ x = -8,5}$
