Question

-8x+(4+8x)=10-x
1,3x-2-(3,3x-5)=2x+1 срочно​

Answer 1

Ответ:

$- 8x + (4 + 8x) = 10 - x \\ - 8x + 4 + 8x = 10 - x \\ 4 = 10 - x \\ x = 10 - 4 \\ x = 6 \\ \\ 1,3x - 2 - (3,3x - 5) = 2x + 1 \\ 1,3x - 2 - 3,3x + 5 = 2x + 1 \\ - 2x + 3 = 2x + 1 \\ - 2x - 2x = 1 - 3 \\ - 4x = - 2 \\ x = \frac{1}{2}$
