Question

9+4(x-12)<8-x помогите решить плиз

Answer 1

$9 + 4(x - 12) < 8 - x \\ 9 + 4x - 48 < 8 - x \\ - 39 + 4x < 8 - x \\ 4x + x < 8 + 39 \\ 5x < 47 \\ x < \frac{47}{5} \\ x < 9 \frac{2}{5} \\ x < 9.4$

Answer 2

Sure, let's solve the inequality step by step. Remember that when solving inequalities, the goal is to isolate the variable (in this case, 'x') on one side of the inequality sign.

1. Distribute the 4 on the left side of the inequality: 9 + 4x - 48 < 8 - x

2. Combine like terms on each side: 4x - 39 < 8 - x

3. Add 'x' to both sides to move all 'x' terms to the left side: 4x + x - 39 < 8

4. Combine the 'x' terms on the left side: 5x - 39 < 8

5. Add 39 to both sides to isolate the '5x' term: 5x < 8 + 39 5x < 47

6. Finally, divide both sides by 5 to solve for 'x': x < 47 / 5 x < 9.4

So, the solution for the inequality is: x < 9.4.
