Worked through step by step. More equations.

Answer
x=9\boxed{x = 9}

Substituting x=9x = 9 back into the original equation gives 7(9)−12=63−12=517(9) - 12 = 63 - 12 = 51, which confirms the result.

Problem: Solve for xx in the equation 7x−12=517x - 12 = 51.

Steps

  1. Add 12 to both sides
    7x=51+127x = 51 + 12
    7x=637x = 63
  2. Divide both sides by 7
    x=637x = \frac{63}{7}
    x=9x = 9
