Answer:
- True
- True
- False
- True
Step-by-step explanation:
- Subtracting the equation will get rid of y variable therefore it's a correct and logical first step to solve the system
- The solution is indeed (-3, -3) as if we substitute these values in both equation, the equation will be correct and valid.
(Correct)
(Correct)
- We have already determined the logical first step. Multiply by -2 will not get rid of any of the variables. Therefore, this is false.
- The solution can be written as one value since x = y = -3. Therefore, this statement is true.
