Question

5-4(2x-7)<-39 need help quiz

Answer 1

$\\ \sf\longmapsto 5-4(2x-7)$

$\\ \sf\longmapsto 5-8x+28$

$\\ \sf\longmapsto -8x+33$

$\\ \sf\longmapsto 8x-33>39$

$\\ \sf\longmapsto 8x>72$

$\\ \sf\longmapsto x>9$

Answer 2

Answer:

x > 9

Step-by-step explanation:

5 - 4(2x - 7) < - 39 ( subtract 5 from both sides )

- 4(2x - 7) < - 44

Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity.

2x - 7 > 11 ( add 7 to both sides )

2x > 18 ( divide both sides by 2 )

x > 9
