Question

What are the solutions of 4x - 9 2?

Answer 1

x<4 and x>4

Explanation:

4x-9<7 or 3x-10>2

Start with 4x-9<7

You want to get the variable alone. Since 9 is negative add it to both sides

4x-9(+9)<7(+9)

4x<16

You have to divide the 4 from both sides for the variable to be alone.

4x(/4)<16/4

x<4

Next 3x-10>2

Get the variable alone.

3x-10(+10)>2(+10)

3x>12

Divide 3 on both sides

3x(/3)>12(/3)

x>4

Answer 2

4/11

Explanation:

4x -9 =2

perform inverse operations

+9 to both sides

4x = 11

divid both sides by 4

x = 4/11
