5 upon X + 1 minus 2 upon Y minus 1 equals to 1 by 2 and 10 upon X + 1 + 2 upon Y minus 1 equals to 5 by 2
Answers
Given: The equations: 5/x+1 - 2/y-1 = 1/2 and 10/x+1 + 2/y-1 = 5/2
To find: The value of x and y.
Solution:
- Let 1/x+1 be u and 1/y-1 be v.
5u - 2v = 1/2 and 10u + 2v = 5/2
10u - 4v = 1 and 20u + 4v = 5
- Solving them, we get:
10u - 4v = 1 .................(i)
20u + 4v = 5 .................(ii)
30u = 6
u = 1/5
- Putting u in (i), we get:
10(1/5) - 4v = 1
2 - 4v = 1
1 = 4v
v = 1/4
- Re substituting the values, we have:
1/x+1 = u = 1/5
x + 1 = 5
x = 4
1/y-1 = v = 1/4
y - 1 = 4
y = 5
Answer:
So the value of x is 4 and y is 5.
Step-by-step explanation:
4 and 5
5÷X+ 1÷y=2
6÷X-3÷y=1
Xis not equal to 0 and y is not equal to 0
