Question

0 5(8x-3)=-0,4(2,5-2x)

Answer 1

Ответ:

X=25/48

Объяснение:

4x-1,5=1-0,8x

4x+0,8x=1+1,5

4,8x=2,5

X=25/48

Answer 2

To solve the equation, let's first distribute the numbers outside the parentheses:

0 + 5(8x - 3) = -0.4(2.5 - 2x)

Now, simplify each side of the equation step by step:

1. Distribute on the left side: 5 * 8x - 5 * 3 = -0.4(2.5 - 2x)

2. Simplify the left side: 40x - 15 = -0.4(2.5 - 2x)

Now, let's distribute on the right side:

-0.4 * 2.5 + 0.4 * 2x = -0.4(2.5 - 2x)

Now, continue simplifying the right side:

-1 + 0.8x = -0.4(2.5 - 2x)

Now, the equation becomes:

40x - 15 = -1 + 0.8x

Next, let's isolate the variable x on one side of the equation. We'll move all terms containing x to the left side and the constant terms to the right side.

Subtract 0.8x from both sides:

40x - 0.8x - 15 = -1

Combine like terms:

39.2x - 15 = -1

Now, add 15 to both sides to eliminate the constant term on the left side:

39.2x = 14

Finally, divide both sides by 39.2 to solve for x:

x = 14 / 39.2

Now, calculate the value of x:

x ≈ 0.3571428571

Rounded to four decimal places:

x ≈ 0.3571
