Question

HELP MEDAL!!!
What is the solution of the system?
7x + 5y = 19
-7x - 2y = -16

I know that I am suppose to use elimination to solve it but I dont understand the example in my text book. HELP!

Answer 1

omg im doing this today >.>

Answer 2

lol

Answer 3

there is an example in my textbook but no help

Answer 4

yes, the elimination method would be the best way to go since it's already set up to eliminate x. first, combine the two equations

Answer 5

how?

Answer 6

7x + 5y=19
x = (19-5y)/7
-7((19-5y)/7) + 5y= 19
solve it ..u get the value of y
simply insert the value of y in 7x + 5y=19 to fine the value of x :)
