How do I solve simultaneous congruence modulo equations

WebSince both equations give y explicitly in terms of x, we can easily substitute either equation into the other one, to get x^2-5x-14 = x-7. Therefore, x^2-6x-7 = 0; (x-7) (x+1) = 0; x-7=0 or x+1=0; x=7 or x=-1. Since y=x-7, it follows that y=0 when x=7, and y=-8 when x=-1. So the solutions are the ordered pairs (7, 0) and (-1, -8). WebApr 3, 2024 · t = h + 1. They each take the reciprocal of their numbers. The sum of the reciprocals is 5 6. 1 h + 1 t = 5 6. And implicitly it gives. h ≠ 0 t ≠ 0. Use algebra to work out Hannah's original number. 5 6 = t + h h t ⇒ 5 6 h t = h + t. The equations are not equivalent, because the second equation would also allow for h = t = 0. bitlocker progress checkWebAdd a comment. 1. Another approach consists in adding the two ODEs : d y + d x d t = x + y + 2 e t = d u d t = u + 2 e t where u = y + x. This first order linear ODE is easy to solve : u = 2 t e t + c 1 e t → y = − x + 2 t e t + c 1 e t. Puting it into the first ODE : d x d t = 3 x − 2 t e t − c 1 e t. bitlocker program for windows 11 download
