Question

8. 10n + 110 = 10
9. 17z + 324 = 35
10. 19 + 8t = 83
11. 35 + 7X = 0
12. 54 + 9X = 0

Answer 1

Simplifying 5x + -54 = 3x + -8 Reorder the terms: -54 + 5x = 3x + -8 Reorder the terms: -54 + 5x = -8 + 3x Solving -54 + 5x = -8 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. -54 + 5x + -3x = -8 + 3x + -3x Combine like terms: 5x + -3x = 2x -54 + 2x = -8 + 3x + -3x Combine like terms: 3x + -3x = 0 -54 + 2x = -8 + 0 -54 + 2x = -8 Add '54' to each side of the equation. -54 + 54 + 2x = -8 + 54 Combine like terms: -54 + 54 = 0 0 + 2x = -8 + 54 2x = -8 + 54 Combine like terms: -8 + 54 = 46 2x = 46 Divide each side by '2'. x = 23 Simplifying x = 23
