Determine whether the equation
- 5 (x + 2 ) + 2 = -3x + 5
is true for all values of x (and hence an identity) or if it is true for only some values of x (and hence a conditional equation.)
| - 5 (x + 2 ) + 2 | = -5x -10 + 2 = -5x - 8 |
Simplify the left hand side and determine if it is identical to the right hand side |
| State an answer. | Is this an identity? |
