Answer 2

Solving the Equations

1. -2x + 19 = 5x - 16 - To solve for x: - First, combine like terms: -2x - 5x = -16 - 19 - Then, solve for x: -7x = -35 - Finally, divide by -7: x = 5

2. 8x - 25 = 3x + 20 - To solve for x: - First, combine like terms: 8x - 3x = 20 + 25 - Then, solve for x: 5x = 45 - Finally, divide by 5: x = 9

3. 6 - y = 3(3y - 8) - To solve for y: - First, distribute the 3: 6 - y = 9y - 24 - Then, combine like terms: y + 9y = 6 + 24 - Finally, solve for y: 10y = 30 - And divide by 10: y = 3

4. 5(y + 1.2) = 7y + 4 - To solve for y: - First, distribute the 5: 5y + 6 = 7y + 4 - Then, combine like terms: 5y - 7y = 4 - 6 - Finally, solve for y: -2y = -2 - And divide by -2: y = 1

5. 4(x - 3) - 16 = 5(x - 5) + 6 - To solve for x: - First, distribute the 4 and 5: 4x - 12 - 16 = 5x - 25 + 6 - Then, combine like terms: 4x - 28 = 5x - 19 - Finally, solve for x: x = -9

6. 3x - 17 = 8x + 18 - To solve for x: - First, combine like terms: 3x - 8x = 18 + 17 - Then, solve for x: -5x = 35 - Finally, divide by -5: x = -7

7. 11 - 5y = 12 - 6y + 8 - To solve for y: - First, combine like terms: 11 + 8 = 12 - 6y + 5y - Then, solve for y: 19 = -y + 6 - Finally, solve for y: y = -13

8. 4y + (11.8 - y) = 3.8 - 5y + 9 - To solve for y: - First, combine like terms: 4y + 11.8 - y = 12.8 - 5y - Then, solve for y: 3y + 11.8 = 12.8 - 5y - Finally, solve for y: 8y = 1 - And divide by 8: y = 1/8

9. 3x + 16 = 8x - 9 - To solve for x: - First, combine like terms: 3x - 8x = -9 - 16 - Then, solve for x: -5x = -25 - Finally, divide by -5: x = 5

I hope this helps! Let me know if there's anything else I can do for you.
