Which value satisfies the inequality (2x-3>7)?

Answer and explanation

Correct answer: (x=6)

The direct answer is A: \(x=6\). Solve first: \(2x-3>7\). Add 3 to both sides: \(2x>10\). Divide by positive 2: \(x>5\). Therefore any value greater than 5 works. Test the options directly: for x=6, \(2(6)-3=12-3=9>7\), so A satisfies the inequality. For x=5, the left side is \(10-3=7\), giving 7>7, which is false; the boundary is not included, so B fails. For x=4, the left side is 5, not greater than 7, so C fails. For x=3, the left side is 3, so D fails. The strict sign > is important: x must be strictly greater than 5, not equal to 5. Memory cue: after solving, substitute each offered value into the original inequality, not a changed form.
