We want to make a system of linear equations that would allow us to find the measure of the angles (we only want to find the system, not solving it)

Here we will find that we do not have a system of linear equations, we have:

s + t = 90°

t < 2*s

Here we have two complementary angles s and t.

Remember that two angles are complementary if their sum is equal to 90°, then we can write:

s + t = 90°

We also know that "t is less than twice s"

this can be written as:

t < 2*s

Notice that the above one is not an equation, is an inequality.

Then the system that we should use to

s + t = 90°

t < 2*s

If we want to force our system to be a system of linear equations, we can write:

s + t = 90°

t = 2*s

But naturally;

s + t = 90°

t < 2*s

has more solutions than:

s + t = 90°

t = 2*s

So we should not replace the inequality with an equation.
