Question

(у+6)-(у-4)=3у 57-3х=0 16х-2=94 -3,3х-99=0 помогите пожалуйста

Answer 1

1)( у + 6 ) - ( у - 4 ) = 3у
у + 6 - у - 4 = 3у
10 = 3у
3у = 10
у = 10/3

2)57 - 3х = 0
- 3х = - 57
х = 19

3)16х - 2 = 94
16х = 94 + 2
16х = 96
х = 6

4) - 3,3х - 99 = 0
- 3,3 = 99
х = - 30

Answer 2

To solve the given equation, let's break it down step by step:

1. Simplify the equation:

(у + 6) - (у - 4) = 3у + 57 - 3х = 0 + 16х - 2 = 94 - 3.3х - 99 = 0

Simplifying each part of the equation, we get:

у + 6 - у + 4 = 3у + 57 - 3х = 0 + 16х - 2 = 94 - 3.3х - 99 = 0

10 = 3у + 57 - 3х = 16х - 2 = -3.3х - 5 = 0

2. Combine like terms:

у - у + 6 + 4 = 3у + 57 - 3х = 0 + 16х - 2 = 94 - 3.3х - 99 = 0

10 = 3у + 57 - 3х = 16х - 2 = -3.3х - 5 = 0

10 = 3у + 57 - 3х = 16х - 2 = -3.3х - 5 = 0

10 = 3у - 3х + 57 = 16х - 2 = -3.3х - 5 = 0

10 = 3у - 3х + 57 = 16х - 2 = -3.3х - 5 = 0

3. Simplify further:

10 = 3у - 3х + 57 = 16х - 2 = -3.3х - 5 = 0

10 = 3у - 3х + 57 = 16х - 2 = -3.3х - 5 = 0

10 = 3у - 3х + 57 = 16х - 2 = -3.3х - 5 = 0

10 = 3у - 3х + 57 = 16х - 2 = -3.3х - 5 = 0

4. Solve for у:

10 = 3у - 3х + 57 = 16х - 2 = -3.3х - 5 = 0

3у - 3х = -47

3у = 3х - 47

у = (3х - 47) / 3

5. Solve for х:

10 = 16х - 2

16х = 12

х = 12 / 16

х = 3 / 4

6. Substitute the value of х back into the equation to find у:

у = (3(3/4) - 47) / 3

у = (9/4 - 47) / 3

у = (-179/4) / 3

у = -179/12

Therefore, the solution to the given equation is у = -179/12 and х = 3/4.
