Study Notes
Solving 2-Step Equations
- Equations: x + 3 = -7, x = -10; x / -2 = 5; 3x = -18
- Order of Operations: When solving equations, follow the order of operations in reverse
- Undoing Operations: To isolate the variable, perform the inverse operation of addition or subtraction first, followed by multiplication or division
-
Example (2n + 7 = 25):
- Subtract 7 from both sides: 2n = 18
- Divide both sides by 2: n = 9
-
Example (x/5 - 4 = -14):
- Add 4 to both sides: x/5 = -10
- Multiply both sides by 5: x = -50
Simplifying Before Solving
- Example (2x - 3x -5): Combine like terms: -x - 5
