Mathematics
Which steps could be part of the process in algebraically solving the system of equations, y + 5x = x2 + 10 and y = 4x – 10? Select two options.
y = x2 + 5x + 10
y + 5x = x2 + 10 + 4x – 10
0 = x2 – 9x
0 = x2 – 9x + 20
One x-value of a solution to the system is 4.

Step-by-step explanation:
3. x= 3x − 5y, y = x − 2y+ t2, x(0) = −1, y(0) = 0, t = 1. 4. x = x + 2y+ cost, y = 5x − 2y, x(0) = 0, y(0) = 1, t = 1. 5. x = x2 − y, y = x + y, x(0) = −1, y(0) = 0, t = 1. 6. x = xy ...
