Question

-12x + 11y = -53
-11x -6y = -129
Solve systems graphically and algebraically

Answer 1

-12x + 11y = -53

×= 4.67

y= -4.81

-11x - 6y = -129

x= 11.73

y= 21.5

Explanation:

-12x + 11 (0) = -53

-12x = -53

-53/-12 = 4.67

4.67 = x

-12(0) + 11y = -53

-53/11 = -4.81

-4.81 = y

________________________________

-11x - 6(0) = -129

-129/-11 = 11.73

11.73 = x

-11(0) -6y = -129

-129/-6y = 21.5

21.5 = y
