Answer:

x = 6

Explanation:

  • Pull out like factors:

-4x - 13 = -1 • (4x + 13)

  • Equation at the end of step 2:

-178 - (-5x + -4 • [4x + 13] ) = 0

  • Pull out like factors:

21x - 126 = 21 • (x - 6)

  • Equation at the end of step 4:

21 • (x - 6) = 0

  • Solve:

x-6 = 0

  • Add 6 to both sides of the equation:

x = 6
