Question

Which steps could be part of the process in algebraically solving the system of equations, y + 5x = x + 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.​

Answer 1

y=x2 + 5x + 10

y + 5x = x2 + 10 + 4x - 10

0 = x2-9x 0 = x2 - 9x + 20
