Solve for 𝑥 in the equation: 5𝑥−7=18.

Answer: 𝑥=6

To solve the equation 5x - 7 = 18, first add 7 to both sides, resulting in 5x = 25. Then, divide both sides by 5, which yields x = 5. Therefore, for the given equation, the correct solution is x=5. The provided answer x=6 would be correct if the equation were 5x - 7 = 23.
