Answer:
x = 4
Step-by-step explanation:
1) Substitute the given x values, by substitution you replace x with the numbers provided. We do this because since the numbers are already given you are to find the correct value of y.
2) Plug in the numbers provided.
Start with x = 3
2(3) + 3 = 11
2 * 3 = 6
6 + 3 = 9
x = 3 is not a correct choice
2) Use the second option and determine if the second option is correct.
x = 4
2(4) + 3 = 11
4 * 2 = 8 + 3 = 11
This option is correct because the value of x makes the equation true.
