х=-3

Пошаговое объяснение:

-3(4-5х)+2(3-6х)=-15

-12+15х+6-12х=-15

15х-12х=12-6-15

3х=-9

х-3

Answer 2

Answer 3

To solve the equation -3(4-5x) + 2(3-6x) = -15, follow these steps:

1. Distribute the constants outside the parentheses to the terms inside:

   -3 * 4 + 3 * 5x + 2 * 3 - 2 * 6x = -15

2. Perform the multiplications:

   -12 + 15x + 6 - 12x = -15

3. Combine like terms by adding and subtracting:

   (-12 + 6) + (15x - 12x) = -15

   -6 + 3x = -15

4. Isolate the variable term by adding 6 to both sides:

   -6 + 6 + 3x = -15 + 6

   3x = -9

5. Finally, divide both sides by 3 to solve for x:

   (3x) / 3 = (-9) / 3

   x = -3

So, the solution to the equation is x = -3.
