Consider the given equations:
(Equation 1)
(Equation 2)
(Equation 3)
Adding equations 1 and 3, we get


So, we get
(Equation 4)
Multiplying equation 3 by '6', we get
(Equation 5)
Subtracting equation 5 from equation 2, we get


(Equation 6)
Multiplying equation 4 by '21' and adding it to equation 6, we get


So, z = -5
Since,

So, y=-5
Now,

So, x = -4
Therefore, x = -4, y= -5 and z= -5 are the solutions to the given equations.
Answer:
5=12
3=? then Criss cross it and you will get 12*3 divided by 5 then you get 7.2
so the answer will be 7 days
The answer is 13/20. So 3/5 is equal to 6/10 so you're looking for the fraction that's half of 7/10 and 6/10 which is 6.5/10 but you can't use decimals in a fraction so you multiply both sides by 10 which would equal 65/100 and simply, and that would be 13/20.

This is because slope intercept from is "Y= mx+b" :)
