Question

solve 43x+67y=-24 and 67x+43y=24

Answer 1

43x+67y=-24
43x=-24-67y
x=(-24-67y)/43-------------(1)

67x+43y=24 ----------------(2)
(1) Sub into (2)

67(-24-67y)+43y=24
-1608-4489y+43y=24
-4446y=1632
y=- $\frac{4446}{1632}$ (simplify it)
y=- $\frac{272}{741}$ 

x=(-24-67(-$\frac{272}{741}$ ))/43
x=-0.5937/43
x=-0.01381
x=- $\frac{440}{31863}$
