Worked practice questions

Solve for z: 3(5z − 7) − 2(9z − 11) = 4(8z − 13) − 17

  1. z = 1
  2. z = 2
  3. z = 3
  4. z = −2
Show answer and solution

Correct answer: B. z = 2

Expand: LHS = 15z − 21 − 18z + 22 = −3z + 1. RHS = 32z − 52 − 17 = 32z − 69. So −3z + 1 = 32z − 69, giving 35z = 70 and z = 2.
