Question

Решите уравнения 8у-9-(4у-5)=12у-(4+5у) 4+8у+8=2у-(10+7у+9)

Answer 1

1)8у-9-4у+5=12у-4-5у
-3у=0
у=0
2)4+8у+8=2у-10-7у-9
13у=-31
у=-31/13

Answer 2

I can help you solve equations. Here is the detailed solution for your equations:

The first equation is $8y-9-(4y-5)=12y-(4+5y)+4$. To solve it, we need to simplify both sides by applying the distributive property and combining like terms. We get:

$8y-9-4y+5=12y-4-5y+4$

$4y-4=7y$

Then we need to isolate y by subtracting 4y from both sides and dividing by 3. We get:

$-4=3y$

$y=-\frac{4}{3}$

The second equation is $8y+8=2y-(10+7y+9)$. To solve it, we need to simplify both sides by applying the distributive property and combining like terms. We get:

$8y+8=2y-10-7y-9$

$8y+8=-5y-19$

Then we need to isolate y by adding 5y to both sides and subtracting 8 from both sides. We get:

$13y=-27$

$y=-\frac{27}{13}$

Therefore, the solutions are $y=-\frac{4}{3}$ for the first equation and $y=-\frac{27}{13}$ for the second equation.Ответь+подробно.+Решите+уравнения++8у-9-(4у-5)=12у-(4+5у)+4+8у+8=2у-(10+7у+9)
