Answer:
25/28
Step-by-step explanation:
1 1/4=5/4
1 2/5=7/5
------------
(5/4)/(7/5)
(5/4)(5/7)
25/28
Given:
The system of equations is


To find:
The missing value for which the given system of equations have infinitely many solutions.
Solution:
Let the missing value be k.
We have,


Taking all the terms on the left side, the given equations can be rewritten as


The system of equations
and
have infinitely many solutions if

We have,


Now,



On cross multiplication, we get


Therefore, the missing value is -10.
Answer:
Y = 2/5z-6/5w
Step-by-step explanation:
6W + 5y = 2z
1. Subtract 6W from both sides
2. 5y = 2z-6W
3. Divide both sides by 5
4. y = 2/5z-6/5W
