What is the solution to the following system of equations? y equals x squared +10 x +11 and y equals x squared plus x -7

Step-by-step explanation:

the system is :

y=x²+10x+11  ...(1)

y=x²+x-7(2)

by (1) and (2) : x²+10x+11 = x²+x-7

10x+11 = x - 7

10x - x = -7 -11

9x = -18

x = -18/9 = -2

put this value in (1) or (2) : y=(-2)²+(-2)-7 = 4 -9 = -5

single solution for this system : (-2 ; -5)

r and t.

both are 64 degrees.
