9+5x<6-4x+12
Use the distributive property to multiply -4 by x-3.
9+5x<18-4x
Add 6 and 12 to get 18.
9+5x+4x<18
Add 4x to both sides.
9+9x<18
Combine 5x and 4x to get 9x.
9x<18-9
Subtract 9 from both sides.
9x<9
Subtract 9 from 18 to get 9.
x<\frac{9}{9}
Divide both sides by 9. Since 9 is positive, the inequality direction remains the same.
x<1
Divide 9 by 9 to get 1.
