a) 5x + 4 -2 > x – 10
b) x -9 < 18
c) 6x -5 > 2x + 3
d) 5 + x < 54 ​

Answer 1

Explicação passo-a-passo:

a) 5x + 4 -2 > x – 10

5x - x > -10 - 4 + 2

4x > -12

x > -12 ÷ 4

x > -3

b) x -9 < 18

x < 18 + 9

x < 27

c) 6x -5 > 2x + 3

6x - 2x > 3 + 5

4x > 8

x > 8 ÷ 4

x > 2

d) 5 + x < 54

x < 54 - 5

x < 49
