Question

0,4*(x-2)=0,5*(4-x)-1,5

Answer 1

Ответ:

1,4

Пошаговое объяснение:

0,4х-0,8=2-0,5х-1,5

0,4х-0,8=0,5-0,5х

0,4х+0,5х=0,5+0,8

0,9х=1,3

х=1,4

Answer 2

To solve the equation 0.4*(x-2) = 0.5*(4-x) - 1.5, follow these steps:

Step 1: Distribute the multiplication on both sides of the equation:

0.4x - 0.42 = 0.54 - 0.5x - 1.5

Step 2: Simplify the terms on both sides:

0.4x - 0.8 = 2 - 0.5x - 1.5

Step 3: Combine like terms on both sides:

0.4x + 0.5x = 2 + 0.8 - 1.5

0.9*x = 1.3

Step 4: Divide both sides by 0.9 to solve for x:

x = 1.3 / 0.9

x ≈ 1.4444

So, the solution to the equation is approximately x = 1.4444.
