See a solution process below:

Explanation:

First, add color(red)(2)2 and subtract color(blue)(3x)3x from each side of the inequality to isolate the xx term while keeping the inequality balanced:

-color(blue)(3x) + 5x - 2 + color(red)(2) > -color(blue)(3x) + 3x + 11 + color(red)(2)3x+5x2+2>3x+3x+11+2

(-color(blue)(3) + 5)x - 0 > 0 + 13(3+5)x0>0+13

2x - 0 > 0 + 132x0>0+13

2x > 132x>13

Now, divide each side of the inequality by color(red)(2)2 to solve for xx while keeping the inequality balanced:

(2x)/color(red)(2) > 13/color(red)(2)2x2>132

(color(red)(cancel(color(black)(2)))x)/cancel(color(red)(2)) > 13/2

x > 13/2

Or

x > 6.5
