Question

0,25х-26,9=1,3+2,6х?

Answer 1

0,25х-26,9=1,3+2,6х

0,25х-2,6х=1,3+26,9

-2,35х=28,2

-х=28,2:2,35

-х=12

х=-12

Проверка:

0,25·(-12)-26,9=1,3+2,6·(-12)

           -3-26,9=1,3-31,2

               -29,9=-29,9

Answer 2

To solve the equation 0.25x - 26.9 = 1.3 + 2.6x, we can start by simplifying the equation:

0.25x - 2.6x = 1.3 + 26.9

Combining like terms:

-2.35x = 28.2

Next, we want to isolate the variable x. We can do this by dividing both sides of the equation by -2.35:

x = 28.2 / -2.35

Calculating the right-hand side:

x ≈ -12

Therefore, the solution to the equation is x ≈ -12.
