Solve
- A.
X = 7 and x = 5
- B.
X = -7 and x = -5
- C.
X = 1 and x = -7
- D.
X = - 8 and x = 4
Correct Answer
B. X = -7 and x = -5Explanation
The given answer x = -7 and x = -5 is correct because these values satisfy the given equations x = 7 and x = 5. When we substitute x = -7 and x = -5 into these equations, we get -7 = 7 and -5 = 5, which are both true. Therefore, x = -7 and x = -5 are the correct solutions to the given equations.Rate this question:

Solve by the grouping method
- A.
X = 5/2 and x = -2/3
- B.
X = 1/2 and x = 3
- C.
X = -2/5 and x = -2/3
- D.
X = -1/3 and x = -5/3
Correct Answer
A. X = 5/2 and x = -2/3Explanation
The given answer x = 5/2 and x = -2/3 is correct because these are the values of x that satisfy the given equation when solved using the grouping method. The grouping method involves grouping the terms in the equation and factoring out common factors to simplify the equation. By using this method, the equation can be rearranged to obtain the values of x that make the equation true.Rate this question:
