Question

3,8x-0,75=0,8x-18,75

Answer 1

3,8х-0,8х=0,75-18,75
3х=-18
Х=-18:3
Х=-6

Answer 2

To solve the equation 3.8x - 0.75 = 0.8x - 18.75, you need to isolate the variable x on one side of the equation. Follow these steps:

Step 1: Group the x terms on one side and the constant terms on the other side.

Start by subtracting 0.8x from both sides of the equation: 3.8x - 0.8x - 0.75 = 0.8x - 0.8x - 18.75

Simplify: 3x - 0.75 = -18.75

Step 2: Isolate the variable term (3x) by moving the constant term (-0.75) to the other side of the equation. To do that, add 0.75 to both sides:

3x - 0.75 + 0.75 = -18.75 + 0.75

Simplify: 3x = -18

Step 3: Finally, solve for x by dividing both sides by 3:

x = -18 / 3

Simplify: x = -6

So, the solution to the equation is x = -6.
