Question

4 - 5 (3x+ 2,5) = 3x + 9,5

Answer 1

4 - 5 (3x+ 2,5) = 3x + 9,5 = 39,5

Answer 2

4-15x-12,5=3x+9,5
-8,5-15x=3x+9,5
-15x-3x=9,5+8,5
-18x=18
x=-1

Answer 3

To solve the equation "4 - 5(3x + 2.5) = 3x + 9.5," follow these steps:

1. Distribute the -5 on the left side of the equation: 4 - 5(3x + 2.5) = 3x + 9.5 4 - 15x - 12.5 = 3x + 9.5

2. Combine like terms on both sides of the equation: (4 - 12.5) - 15x = 3x + 9.5 -8.5 - 15x = 3x + 9.5

3. To isolate the variable terms (x terms) on one side of the equation, you can add 15x to both sides to move the x terms to the left side: -8.5 - 15x + 15x = 3x + 15x + 9.5

4. Simplify both sides of the equation: -8.5 = 18x + 9.5

5. Next, subtract 9.5 from both sides to isolate the x terms on the right side: -8.5 - 9.5 = 18x + 9.5 - 9.5

6. Simplify further: -18 = 18x

7. Finally, divide both sides by 18 to solve for x: -18 / 18 = 18x / 18

8. The solution is: x = -1

So, the solution to the equation is x = -1.
