This is because simplifying the equation before solving it will lead you to the answer at a much faster rate. For example, in the given equation, the long way would be to distribute 2 to (x+3). Then, you transpose them and combine like terms. Until you get to x + 3 = 8. But if you simplify it first, you will see that it is straightforward. It will lead you to the answer right away which is x + 3 = 8. It saves you from the hassle of doing more algebra :)

Answer:
Both angles are right angles.
Step-by-step explanation:
Supplementary angles sum to 180°. Since we know that both angles are congruent, let's call them x and x. We can write the following equation:
x + x = 180
2x = 180
x = 90°
Therefore, we can conclude that both angles are right angles.
