Question

3•(Х-2) = 10-Х 6•(b-3) = 10-2•(b+2) 83+5•(y-3) = 3•(8y-9) Помогите

Answer 1

3х-6=10-х
4х=16
х=4

6в-18=10-2в+4
8в=10+4+18
в=32:8
в=4

83+5у-15=24у-27
83-15+27=24у-5у
95=19у
у=95:19=5

Answer 2

X = 4
b = 2
у = 5

Удачи!!! :)

Answer 3

Equation 1: 3•(Х-2)+=+10-Х

To solve the equation 3•(Х-2)+=+10-Х, we can follow these steps:

1. Distribute the 3 on the left side of the equation: - 3•Х - 3•2 + = + 10 - Х

2. Combine like terms: - 3•Х - 6 + = + 10 - Х

3. Simplify the equation by combining the Х terms: - 3•Х + Х - 6 = 10

4. Combine like terms: - 4•Х - 6 = 10

5. Add 6 to both sides of the equation to isolate the Х term: - 4•Х = 10 + 6

6. Simplify: - 4•Х = 16

7. Divide both sides of the equation by 4 to solve for Х: - Х = 16/4

8. Simplify: - Х = 4

Therefore, the solution to the equation 3•(Х-2)+=+10-Х is Х = 4.

Equation 2: 6•(b-3)+=+10-2•(b+2)+83

To solve the equation 6•(b-3)+=+10-2•(b+2)+83, we can follow these steps:

1. Distribute the 6 on the left side of the equation: - 6•b - 6•3 + = + 10 - 2•(b+2) + 83

2. Combine like terms: - 6•b - 18 + = + 10 - 2•b - 2•2 + 83

3. Simplify the equation by combining the b terms: - 6•b - 2•b - 18 + = + 10 - 2•2 + 83

4. Combine like terms: - 4•b - 18 + = + 10 - 4 + 83

5. Simplify: - 4•b - 18 + = + 89

6. Add 18 to both sides of the equation to isolate the b term: - 4•b = 89 + 18

7. Simplify: - 4•b = 107

8. Divide both sides of the equation by 4 to solve for b: - b = 107/4

9. Simplify: - b = 26.75

Therefore, the solution to the equation 6•(b-3)+=+10-2•(b+2)+83 is b = 26.75.

Equation 3: 5•(y-3)+=+3•(8y-9)

To solve the equation 5•(y-3)+=+3•(8y-9), we can follow these steps:

1. Distribute the 5 on the left side of the equation: - 5•y - 5•3 + = + 3•(8y-9)

2. Combine like terms: - 5•y - 15 + = + 3•8y - 3•9

3. Simplify the equation by combining the y terms: - 5•y + 15 + = + 24y - 27

4. Combine like terms: - 5•y + 15 + = + 24y - 27

5. Simplify: - 5•y + 15 + = + 24y - 27

6. Subtract 5•y from both sides of the equation to isolate the y term: - 15 = 24y - 5•y - 27

7. Simplify: - 15 = 19y - 27

8. Add 27 to both sides of the equation: - 15 + 27 = 19y - 27 + 27

9. Simplify: - 42 = 19y

10. Divide both sides of the equation by 19 to solve for y: - y = 42/19

Therefore, the solution to the equation 5•(y-3)+=+3•(8y-9) is y = 42/19.
