Question

-2*(3x-1)+3*(1,2x+1)=-14,5

Answer 1

Решение:

-2(3x-1)+3(1,2x+1)=-14,5

-6х+2+3,6х+3=-14,5

-2,4х+5=-14,5

-2,4х=-14,5-5

-2,4х=-19,5

-х=-19,5÷2,4

-х=-8,125

х=8,125

Ответ: х=8,125

Answer 2

To solve for the value of x in the equation -2*(3x-1)+3*(12x+1) = -14.5, follow these steps:

1. Start by simplifying the equation:

-2*(3x-1) + 3*(12x+1) = -14.5

Distribute the constants and variables:

-6x + 2 + 36x + 3 = -14.5

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

(36x - 6x) + (2 + 3) = -14.5

30x + 5 = -14.5

3. Now, isolate the variable term (30x) by moving the constant term (5) to the other side of the equation. To do this, subtract 5 from both sides:

30x = -14.5 - 5

30x = -19.5

4. Finally, divide both sides by 30 to solve for x:

x = (-19.5) / 30

x = -0.65

So, the solution for the equation -2*(3x-1)+3*(12x+1) = -14.5 is x = -0.65.
