Question

2,91:(1,4х-0,2)=19,4​

Answer 1

Ответ:

Пошаговое объяснение:

1,4x-0,2=2,91:19,4

1,4x-0,2=0,15

1,4x=0,15+0,2

1,4x=0,35

x=0,35:1,4

x=0,25

Answer 2

To solve the equation 2,91:(1,4x - 0,2) = 19,4, let's follow these steps:

Step 1: Simplify the equation. Start by multiplying both sides of the equation by (1.4x - 0.2) to eliminate the fraction:

2.91 = 19.4(1.4x - 0.2)

Step 2: Distribute the multiplication. Apply the distributive property on the right side of the equation:

2.91 = 19.4 * 1.4x - 19.4 * 0.2

Simplify:

2.91 = 27.16x - 3.88

Step 3: Move constants to one side and variables to the other side. Subtract 27.16x from both sides and add 3.88 to both sides to isolate the variable x:

2.91 - 3.88 = 27.16x - 27.16x

-0.97 = -26.16x

Step 4: Solve for x. Divide both sides of the equation by -26.16:

x = -0.97 / -26.16

x ≈ 0.037

Therefore, the approximate solution for the equation 2.91:(1.4x - 0.2) = 19.4 is x ≈ 0.037.
