0.6x+ x ¡Ü1.4x-1

can't read your typing.

Using Encoding of GB2312, the question reads:

0.6x+ x ≤ 1.4x-1
1.6x ≤ 1.4x -1
0.2x ≤ -1
x ≤ -5

To solve the given inequality, we'll need to isolate the variable x. Here are the steps to get the answer:

1. Begin by simplifying both sides of the inequality.
0.6x + x ≤ 1.4x - 1

2. Combine like terms on both sides. (Combine the x terms and the constant terms separately)
1.6x ≤ 1.4x - 1

3. Next, we'll isolate the x terms on one side of the inequality. We can do this by subtracting 1.4x from both sides of the inequality. (Remember, when we move a term to the other side of the inequality, the operation changes its sign)
1.6x - 1.4x ≤ -1

4. Simplify the left side of the inequality.
0.2x ≤ -1

5. Now, we need to get x alone. Divide both sides of the inequality by 0.2. (Since we are dividing by a positive number, there is no need to change the direction of the inequality sign)
(0.2x) / 0.2 ≤ -1 / 0.2
x ≤ -5

Therefore, the solution to the inequality 0.6x + x ≤ 1.4x - 1 is x ≤ -5.
