Solution
Sure, let's solve the inequality step by step:
4x - 2(3x - 9) ≤ -4(2x - 9)
First, distribute the 2 and -4 inside the parentheses:
4x - 6x + 18 ≤ -8x + 36
Then, simplify the equation by combining like terms:
-2x + 18 ≤ -8x + 36
Next, add 8x to both sides of the inequality to get the x terms on one side:
6x + 18 ≤ 36
Then, subtract 18 from both sides to isolate the x term:
6x ≤ 18
Finally, divide both sides by 6 to solve for x:
x ≤ 3
So, the solution to the inequality 4x - 2(3x - 9) ≤ -4(2x - 9) is x ≤ 3.
