Question

-5x+7y=-34
-5x+3y=-6

Answer 1

x = -3, y = -7

Explanation:

-5x + 7y = -34 ⇒ -5x = -34 - 7y

-5x + 3y = -6

-34 - 7y + 3y = -6

-34 - 4y = -6 {add 34 to both sides}

-4y = 28 {divide both sides by (-4)}

y = - 7

-5x + 3y = -6

-5x + 3(-7) = -6

-5x - 21 = -6 {add 21 to both sides}

-5x = 15 {divide both sides by (-5)}

x = -3
