The first step in solving this problem is to use the necessary mathematics to isolate the a term on one side of the inequality and the constants on the other side of the inequality while keeping the inequality balanced:
4a - 2 + color(red)(2) > 14 + color(red)(2)
4a + (- 2 + color(red)(2)) > 14 + color(red)(2)
4a + (0) > 14 + color(red)(2)
4a > 14 + 2
Now combine the like terms, in this case the constants:
4a > 16
Finally, solve for a while keeping the inequality balanced:
(4a)/color(red)(4) > 16/color(red)(4)
(color(red)(cancel(color(black)(4)))a)/color(red)(cancel(color(black)(4))) > 4
a > 4
