Question

(3,2у - 1,8) - (5,2у + 3,4) = -5,8

Answer 1

(3,2у - 1,8) - (5,2у + 3,4) = -5,8
3.2y - 1,8 - 5,2y - 3,4 = - 5,8
- 2y + 5,2 = - 5,8
- 2y = - 5,8 - 5,2
- 2y = - 11    : (-2)
y = 11/2 = 5 1/2
y = 5,5

Answer 2

$(3.2y-1.8)-(5.2y+3.4)=-5.8 \\ 3.2y-1.8-5.2y-3.4=-5.8 \\ -2y-5.2=-5.8 \\ -2y=-5.8+5.2 \\ -2y=-0.6 \\ y=0.3$

Answer 3

It seems like you want to solve the equation:

(3.2y - 1.8) - (5.2y + 3.4) = -5.8

Let's simplify this equation step by step:

First, distribute the negative sign on the right side:

3.2y - 1.8 - 5.2y - 3.4 = -5.8

Now, combine like terms by grouping the y terms and the constants separately:

(3.2y - 5.2y) - (1.8 - 3.4) = -5.8

Simplify each group:

-2y - (-1.6) = -5.8

Now, simplify the negative sign in front of -1.6:

-2y + 1.6 = -5.8

To isolate the variable y, you can subtract 1.6 from both sides of the equation:

-2y + 1.6 - 1.6 = -5.8 - 1.6

-2y = -7.4

Finally, divide both sides by -2 to solve for y:

(-2y)/(-2) = (-7.4)/(-2)

y = 7.4 / 2

y = 3.7

So, the solution to the equation is y = 3.7.
