Q. Which equation has the solution x=3 x=3 ?\newline6x+8=26 6 x+8=26 \newline8x−8=88 8 x-8=88 \newline4x+8=−20 4 x+8=-20 \newline5x−6=3 5 x-6=3
  1. Test Solution x=3x=3: Test the solution x=3x=3 in the first equation 6x+8=266x+8=26.\newlineSubstitute xx with 33 in the equation.\newline6(3)+8=266(3) + 8 = 26\newline18+8=2618 + 8 = 26\newline26=2626 = 26\newlineCheck if both sides are equal.
  2. Substitute xx with 33: Since the first equation holds true for x=3x=3, we have found the equation with the solution x=3x=3. We do not need to test the other equations as we have already found the correct one.
