Question

6y+4 8-5y ——— + ——— = 5 4 3

Answer 1

Ответ:(6у + 7)/4 + (8 - 5у)/3 = 5

3(6у + 7)/12 + 4(8 - 5у)/12 = 5·12/12

3(6у + 7) + 4(8 - 5у) = 5·12

18у + 21 + 32 - 20у = 60

53 - 2у = 60

2у = -7

 у = -3,5

Answer 2

It seems like you're trying to solve an algebraic equation with fractions. To solve this equation, let's first simplify and then isolate the variable. The equation you provided is:

(6y + 4)/8 - (5y)/4 + 3/5 = 5/3

To simplify this equation, you can start by finding a common denominator for the fractions on the left side. The common denominator for 8, 4, and 5 is 40, so you can rewrite the equation as follows:

(5(6y + 4))/40 - (10y)/40 + (24)/40 = 5/3

Now, combine the fractions on the left side of the equation:

(30y + 20 - 10y + 24)/40 = 5/3

Combine like terms in the numerator:

(20y + 44)/40 = 5/3

Now, you can cross-multiply to solve for y:

3(20y + 44) = 5(40)

Now, distribute on both sides:

60y + 132 = 200

Next, subtract 132 from both sides:

60y = 200 - 132 60y = 68

Finally, divide by 60 to isolate y:

y = 68/60 y = 17/15

So, the solution to the equation is:

y = 17/15
