Question

LU 1- 2x + 3 < 5 and - 4x – 3 > 9​

Answer 1

Answer: x>-1

               x<-3

Step-by-step explanation:

$-2x+3$

subtract 3 on both sides

$-2x$

divide -2 on both sides

$x>-1$

The sign changed because I divided by a negative.

$-4x-3>9$

add 3 on both sides

$-4x>12$

multiply -1 on both sides

$4x$

divide 4 on both sides

$x$

Answer 2

Answer:

x > -1

x < -3

Step-by-step explanation:

-2x + 3 < 5

Subtract 3 on both sides.

-2x < 5 - 3

-2x < 2

Divide -2 into both sides.

x < 2/-2

x > -1

-4x - 3 > 9

Add 3 on both sides.

-4x > 9+3

-4x > 12

Divide -4 into both sides.

x > 12/-4

x < -3
