Question

How do you write the the ordered pair that is the solution to the following system of equations: 5x - 2y = 3 and 3x + 4y = 7?

Answer 1

(5x - 2y = 3) *2

10x - 4y =6

3x + 4y = 7

- - -

___________

7x=-1

X=-1/7

put in

5x - 2y = 3

5*-1/7 - 2y=3

-5/7-2y=3

-2y=3+5/7

-2y=27/7

y=27/14
