The answer is H which is 9.

Work Step by Step

To solve the equation for the solution, we need to solve for the value of x and to do that we need to get the function in terms of x so: 4x - 5 = 2x + 13. --> subtract 2x from both sides 4x-2x-5 = 2x-2x+13 2x-5 = 13 --> add 5 to both sides 2x-5+5 = 13+5 2x = 18 --> divide both sides by 2 x=9 Therefore the answer is H which is 9.
