Which of the following is a solution of the equation 5x + 4 = 14?
A. 2
B. -2
C.3
D.1
5x + 4 = 14
5x = 10
x = ?
To determine which of the given options is a solution to the equation 5x + 4 = 14, we can substitute each option into the equation and check if it satisfies the equation.
A. Substitute 2 into the equation: 5(2) + 4 = 14. This simplifies to 10 + 4 = 14, which is not true since 14 ≠ 14. Therefore, 2 is not a solution.
B. Substitute -2 into the equation: 5(-2) + 4 = 14. This simplifies to -10 + 4 = 14, which is not true since -6 ≠ 14. Therefore, -2 is not a solution.
C. Substitute 3 into the equation: 5(3) + 4 = 14. This simplifies to 15 + 4 = 14, which is not true since 19 ≠ 14. Therefore, 3 is not a solution.
D. Substitute 1 into the equation: 5(1) + 4 = 14. This simplifies to 5 + 4 = 14, which is not true since 9 ≠ 14. Therefore, 1 is not a solution.
Since none of the options satisfy the equation 5x + 4 = 14, there is no solution among the given options.
