Question

3.(1 - 2 X) < 2. (X + 1) + X - 7

Answer 1

Resposta:

$3 \times (1 - 2x) < 2 \times(x + 1) + x - 7 \\ 3 \times ( - 1x) < 2 \times (2x) + x - 7 \\ 3 \times 1x < 2 \times 2x + x - 7 \\ 3x < 5x - 7 \\ 8x - 7 \\ 1x$

Answer 2

Resposta:

3 (1-2x) < 2 (x + 1) + x - 7

3 -6x < 2x +2 +x -7

-6x -2x -x < 2 -7 -3

-9x < -8 .(-1)

+9x > +8

x > 8/9
