d)14×-18<4×+32
e)3×-8<22
Me ajudem nessas pfvr ​

Answer 1

Explicação passo-a-passo:

c)

$\sf 24x-8x-10 < 18x+2$

$\sf 16x-10 < 18x+2$

$\sf 18x-16x > -10-2$

$\sf 2x > -12$

$\sf x > \dfrac{-12}{2}$

$\sf x > -6$

d)

$\sf 14x-18 < 4x+32$

$\sf 14x-4x < 32+18$

$\sf 10x < 50$

$\sf x < \dfrac{50}{10}$

$\sf x < 5$

e)

$\sf 3x-8 < 22$

$\sf 3x < 22+8$

$\sf 3x < 30$

$\sf x < \dfrac{30}{3}$

$\sf x < 10$
