Question

5(3x-6)+4(3-2х)=5х-8

Answer 1

Ответ:

5(3x-6)+4(3-2х)=5х-8

15х-30+12-8х=5х-8

15х-8х-5х= -8+30-12

2х=10

х=10:2

х=5

Ответ: х=5

Answer 2

To solve the equation 5(3x-6) + 4(3-2x) = 5x - 8, you can follow these steps:

1. Distribute the numbers outside the parentheses to the terms inside the parentheses.

5 * 3x - 5 * 6 + 4 * 3 - 4 * 2x = 5x - 8

This simplifies to:

15x - 30 + 12 - 8x = 5x - 8

2. Combine like terms on both sides of the equation.

(15x - 8x) - (30 - 12) = 5x - 8

This further simplifies to:

7x - 18 = 5x - 8

3. Now, isolate the variable x on one side of the equation. You can do this by subtracting 5x from both sides of the equation.

(7x - 5x) - 18 = -8

2x - 18 = -8

4. Next, add 18 to both sides of the equation to isolate 2x.

2x - 18 + 18 = -8 + 18

2x = 10

5. Finally, divide both sides by 2 to solve for x.

2x / 2 = 10 / 2

x = 5

So, the solution to the equation is x = 5.
