Question

Which ordered pair is a solution of the equation? 7x-2y=-57x−2y=−5

Answer 1

Since 7x-2y=-57x−2y=−5
eqn 1 ) 7x-2y=−5
eqn 2) -57x−2y=−5
solve equation 1 for x and plugged into equation 2... x=-5/7+2y/7

-57(-5/7+2y/7)−2y=−5
40.714 -16.286y - 2y =-5
40.714-14.286y = -5

40.714-14.286y = -5
- 40.714 and ÷-14.286 from both sides
y=-3.199

And plug y into equation
x=-5/7+2(3.1999)/7 =0.19997
