Solve 5x – 2 > 3x + 11.

We need to solve this inequality to find the value that x could be greater or less than. First, we need to find the smallest positive x value, which is 3x. Then, we minus 3x from both sides, so only one side has an x. Doing this gives  2x - 2 > 11 Now, we need to move all the numbers without an x to the side without the x. Therefore, we add 2 to both sides. Doing this gives 2x > 13 Finally, we need to have the x by itself. Therefore, we need to divide each side by the number in front of the x, which is 2. Doing this gives us x > 6.5 This is the answer.
