Study Notes
Solving Equations
- Solving for x in 8x - 9 = x + 9 yields x = 18/7.
- For the equation 5x + 1 = 7x - 2, the solution is x = -3/2.
- The equation -3x + 25 + x + 21 = 2 simplifies to x = 22.
Evaluating Expressions
- Evaluate 8y + 4 for y = 7 results in 60.
- For x = 8, 6(x-6)+4 evaluates to 16.
- Evaluating n*3 + 27/3 for n = 3 gives 18.
- The expression -|-12| evaluates to -12.
Simplifying Expressions
- 7*7 + 15 - 6/2 simplifies to 61.
- Simplifying -4 + (-13) results in -17.
- The product (-7)(5)(6) simplifies to -210.
- Simplifying the expression -4(x - 4) results in -4x + 16.
- The expression 8x + 4 + 2x - 7 simplifies to 10x - 3.
