Question

45x+67y= -24
67x+43y= 24

Answer 1

Answer:

x=0.22

y=0.20

Step-by-step explanation:

45x=-24- 67y

x= -24 -67 y/45 (whole divide by 45)

67x= 24-43y

x=24-43y/67 (whole divide by 67)

(equalling the value of both the X)

x= -24-67y/45

24-43y/67= -24 -67y/45

1080-1935y = 1608 - 4489y

4489y - 1935y =1608 -1080

2554y = 528

y= 528/2554

y= 0.20

x=24-43y/67

x=24-8.6/67

x=15.4/67

x=0.22
