To solve the equation , follow these steps:
Case 1: Assume .
Simplify the equation:
Subtract from both sides:
Subtract 3 from both sides:
.
Case 2: Assume .
Simplify the equation:
Add to both sides:
Add 1 to both sides:
Divide everything by 3:
.
Therefore, the solutions to the equation are and .
These solutions correspond to answer choice 4: , .
Thus, and .
,
\( \left|x\right|=5 \)
Because absolute value makes expressions positive! When , the expressions inside could be equal OR opposite. That's why we get two cases to solve.
It doesn't matter! You can solve Case 1: x-1 = 2x+3 or Case 2: x-1 = -(2x+3) in any order. Just make sure you solve both cases.
Sometimes absolute value equations produce extraneous solutions. Always substitute each answer back into the original equation. If it doesn't make both sides equal, discard that solution.
Yes! Sometimes neither case produces a valid solution. That's why checking your work is crucial - it tells you which solutions are real and which are extraneous.
Both work! The property means a = b OR a = -b. You could write it as x-1 = -(2x+3) or -(x-1) = 2x+3 - they're equivalent and give the same answer.
