Question

7(6 - 5t) - 5< 1-41t;
-0,5(8x + 9) - 0,9 > 4x-3​

Answer 1

Ответ:

t < -6; x < -0.3

Пошаговое объяснение:

$42 - 35t - 5 < 1 - 41t \\ 37 - 35t < 1 - 41t \\ 37 - 35t + 41t < 1 \\ - 35t + 41t < 1 - 37 \\ 6t < 1 - 37 \\ 6t < - 36 \\ t < - 6$

$- 4x - 4.5 - 0.9 > 4x - 3 \\ - 4x - 5.4 > 4x - 3 \\ - 4x - 4x - 5.4 > - 3 \\ - 4x - 4x > - 3 + 5.4 \\ - 8x > - 3 + 5.4 \\ - 8x > 2.4 \\ x < - 0.3$

Answer 2

Ответ:

1)42-35t-5<1-41t

37-35t+41t<1

-35t+41t <1-37

6t <-36

t <-6

2)-4x-4,5-0,9>4x-3

-4x-5,4>4x-3

-4x-4x>-3+5,4

-8x>2,4
