Question

2) Find x and y 105⁰
​

Answer 1

Answer:

x=-10, y=115, z=90

Step-by-step explanation:

x+y=105 equation 1

y+z=205 equation 2

z+x=80 equation 3

from equation 1,2, and, 3, we deduce

the value of x, y and z in equation Formate is form

x=105-y equation 4

y=105=x equation 5

z=80-x equation 6

substituting the value of y as mentioned equation 5,is equation 2, we get

105-x+z=205

z-x205-105

z-x=100 equation 7

Adding equation 7 and equation 3

z-x=100

z+x=80

2z=180

z=90

substituting the value of equation 3 we get

90+x=80

x=80-90=10

x=10

substituting the value of x equation 1 we get

-10+y=105

y=105+10

y=115

Therefore,

x=10

y=115

z=90
