Which value satisfies 4x - 2 > 10?

Answer and explanation

Correct answer: x = 4

The governing concept is solving and checking a strict linear inequality. Starting with 4x − 2 > 10, add 2 to both sides to obtain 4x > 12. Divide by the positive number 4, giving x > 3. Among the choices, only x = 4 is greater than 3, so option C is correct. Direct substitution confirms it: 4(4) − 2 = 14, and 14 > 10 is true. At x = 3, the expression equals 10, but equality is not allowed because the symbol is strictly >. At x = 2 and x = 1, the expressions are 6 and 2, respectively, and both fail the condition. The boundary value 3 is excluded.
