All are favourite for me ....
45 + 3x and 108 - 4x
45 + 3x = 108 - 4x
3x = 108 - 45 - 4x
3x = 63 - 4x
9x = 63
x = 63/9
x = 7

nose inglés ay pa la próxima
Step-by-step explanation:
Substitute 15 in place of all your x and set up the following:
(4*15+4)^2 + (3*15)^2 = c^2
64^2 + 45^2 = c^2
4096 + 2025 = c^2
