Given the system of equations, what is the solution?
x + 2y = 7
x - 2y = -1
1 answer:
Add the 2 equations to eliminate the 2y. We get
2x = 6
x = 3
Plug x = 3 into the first equation:-
3 + 2y = 7
2y = 7 - 3 = 4
y = 2
Answer is x = 3 and y = 2

Huh
Neat
We can't see it though
1) one mile is 5280 feet
2) 40 x 5280 = 211,200 feet per hour
hopefully i'm right
