Question 11
Linear and Simultaneous Equations(2x − 1)/3 − (3x − 1)/4 = 1, find x
- A.−13
- B.6
- C.13
- D.−6
Show the answer and explanation
Answer: A (−13)
Explanation
Multiply by 12: 4(2x − 1) − 3(3x − 1) = 12, so −x − 1 = 12 and x = −13.
(2x − 1)/3 − (3x − 1)/4 = 1, find x
Answer: A (−13)
Multiply by 12: 4(2x − 1) − 3(3x − 1) = 12, so −x − 1 = 12 and x = −13.
