Question

a) 3x + 4 > x + 10 b) 5 (x - 2) + 2 ( x + 3) < 3 ( x - 7)

Answer 1

Explicação passo-a-passo:

$a)3x + 4 > x + 10 \\ 3x - x > 10 - 4 \\ 2x > 6 \\ \\ b)5.(x - 2) + 2.(x + 3) < 3.(x - 7) \\ 5x - 10 + 2x + 6 < 3x - 21 \\ 5x + 2x - 3x < - 21 + 10 - 6 \\ 4x < - 17$

Answer 2

Oie, Td Bom?!

a)

3x + 4 > x + 10

3x - x > 10 - 4

2x > 6

x > 6/2

x > 3

b)

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

5x - 10 + 2x + 6 < 3x - 21

7x - 4 < 3x - 21

7x - 3x < - 21 + 4

4x < - 17

x < - 17/4
