Question

0,5(0,5х-5/7)=3,5х+1,5

Answer 1

Ответ:

0,5(0,5х - 5/7) = 3,5х + 1,5

0,25х - 25/70 = 3,5х + 1,5

0,25х - 3,5х = 1,5 + 25/70

-3,25х = 15/10 + 25/70

-3,25х = 105/70 + 25/70

-3,25х = 130/70

-3,25х = 13/7

(- 325/100)х = 13/7

(- 13/4)х = 13/7

х = - 4/7

Answer 2

It looks like you've provided an equation. Let's solve it step by step.

The equation you've given is:

0.5(0.5x - 5/7) = 3.5x + 1.5

Let's solve for x:

Step 1: Distribute the 0.5 on the left side of the equation: 0.25x - (5/7) * 0.5 = 3.5x + 1.5

Step 2: Simplify the left side of the equation: 0.25x - 2.5/7 = 3.5x + 1.5

Step 3: Convert 2.5/7 to a decimal: 0.25x - 0.3571 ≈ 3.5x + 1.5

Step 4: Move the x terms to one side and the constant terms to the other side: 0.25x - 3.5x ≈ 1.5 + 0.3571

Step 5: Combine the x terms and the constant terms separately: -3.25x ≈ 1.8571

Step 6: Divide both sides by -3.25 to solve for x: x ≈ 1.8571 / -3.25 x ≈ -0.5705

So, the approximate solution for the equation is x ≈ -0.5705.
