How do i solve this? <br><br> 7 < 3 - 2x<br><br><br> It's linear inequalities

Natasha2012 [34]

Hello from MrBillDoesMath!

Answer:

x < -2

Discussion:

7 < 3 - 2x => Add 2x to both sides

7 + 2x < 3 - (2x - 2x) => As 2x -2x = 0

7 + 2x < 3 => Subtract 7 from both sides

(7-7) + 2x < 3 - 7 => As 7-7 = 0 and 3-7 = -4

2x < -4 => Divide both sides by 2

x < -4./2 = -2

Thank you,

MrB
