Hey there!
12 - 3 > 9
Rewrite the equation: -3x + 12 > 9
SUBTRACT by 12 on your sides
-3x + 12 - 12 > 9 - 12
Cancel out: 12 - 12 because it gives you 0
Keep: 9 - 12 because it helps us solve for our equation
9 - 12 = -3
New equation: -3x > -3
DIVIDE by -3 on your sides
-3x/3 > -3/-3
Cancel out: -3x/-3 because it doesn't give us what's being compared to the x
Keep: -3/-3 because it gives us our answer
-3/-3 = -3 ÷ -3 = 1
Thus your answer is: x < 1
Good luck on your assignment and enjoy your day!
