Question

4,2y+0,8=6,2y-(1,1y+0,8)+0,7

Answer 1

Ответ:

Пошаговое объяснение:

4,2y+0,8 = 6,2y-1,1y-0,8+0,7

4,2y+0,8 = 5,1y-0,8+0,7

4,2y-5,1y = -0,8+0,7-0,8

-0,9y = 0,9

y = -1

Answer 2

To solve the equation, we need to simplify and combine like terms on both sides of the equation. Let's start by doing that step-by-step:

1. Combine like terms on the right side of the equation: 6.2y - (1.1y + 0.8) + 0.7

To remove the parentheses, distribute the negative sign: 6.2y - 1.1y - 0.8 + 0.7

Combine like terms: (6.2y - 1.1y) + (0.7 - 0.8) 5.1y - 0.1

Now, the equation becomes: 4 + 2y + 0.8 = 5.1y - 0.1

2. Move all terms with y to one side of the equation and constant terms to the other side: First, let's move 2y to the left side by subtracting 2y from both sides: 4 + 0.8 = 5.1y - 2y - 0.1

Simplify: 4.8 = 3.1y - 0.1

3. Now, move the constant term (-0.1) to the left side by adding 0.1 to both sides: 4.8 + 0.1 = 3.1y - 0.1 + 0.1

Simplify: 4.9 = 3.1y

4. Finally, solve for y by dividing both sides by 3.1: y = 4.9 / 3.1 y ≈ 1.58

So, the solution to the equation is approximately y = 1.58.
