Answer:
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
