Worked through step by step. More equations.

Answer
x=−1\boxed{x = -1}

Substituting x=−1x = -1 back into the original equation gives 7−2(−1−3)=7−2(−4)=7+8=157 - 2(-1 - 3) = 7 - 2(-4) = 7 + 8 = 15, which confirms the result is correct.

Problem: Solve for xx in the equation 7−2(x−3)=157 - 2(x - 3) = 15.

Steps

  1. Distribute
    7−2x+6=157 - 2x + 6 = 15
  2. Combine like terms
    13−2x=1513 - 2x = 15
  3. Subtract 13 from both sides
    −2x=2-2x = 2
  4. Divide both sides by -2
    x=−1x = -1
