Question

15(-4+у)+(-2)(у+(-9))+5(у+6)=0

Answer 1

15(-4+y)+(-2)(y+(-9))+5(y+6)=0
  -60+15y+(-2)(y-9)+5y+30=0
  -60+15y+(-2y+18)+5y+30=0
    -60+15y-2y+18+5y+30=0
        15y-2y+5y=60-18-30
                    18y=12
                      y=²/₃
Ответ : ²/₃.

Answer 2

Let's solve the equation step by step:

15(-4 + у) + (-2)(у + (-9)) + 5(у + 6) = 0

To simplify, let's start by distributing the coefficients:

15(-4) + 15у + (-2)у + 2(9) + 5у + 5(6) = 0

Now simplify the expressions within parentheses and perform the multiplications:

-60 + 15у - 2у + 18 + 5у + 30 = 0

Combine like terms:

15у - 2у + 5у + (-60 + 18 + 30) = 0

Simplify further:

18у - 12 = 0

Add 12 to both sides to isolate the variable:

18у = 12

Divide both sides by 18 to solve for у:

у = 12/18

Simplify the fraction:

у = 2/3

Therefore, the solution to the equation is у = 2/3.
