Asked in Maths and Science Reasoning Mock

Which of the following shows correct value of x, such that the two expressions given below are equal.I) a+b - c/x + 4c - 3a + 2b/bII) a+b + 4c + 2b/b - c/a - 3a

Correct answer: C. a

  • A. b
  • B. c
  • C. a
  • D. 2

Explanation

Equate both the expressions a+b - c/x + 4c - 3a + 2b/b = a+b + 4c + 2b/b - c/a - 3a Solve for the value of x. Combine like terms: a - 3a + b + 4c -c/x + 2b/b = a - 3a + b + 4c +2b/b - c/a Simplify further: -2a + b + 4c - c/x + 2 = -2a + b + 4c + 2 - c/a Now, subtract −2a+b+4c+2 from both sides to isolate the c/x term: c/x = -c/a Finally, divide both sides by −c to solve for x: x=a
