One angle is five less than three times the size of another angle. together they have a sum of 143 degrees. what are the sizes of each angle?

Let the size of one angle be x
so the size of another angle = 3x-5
sum of the two angles = 143 degrees
so, x + 3x - 5 = 143
or, 4x = 143+5
or, x = 149/4 = 37.25 degrees
other angle = 3*37.25-5 = 106.75 degrees

What is the inequality?
