correct Question:
- x + 1 = 10y
- x-3 = y
Solve for x and y.
Solution:
x + 1 = 10y
=> x = 10y - 1
put the value of x in x-3 = y
=> 10y - 1 - 3 = y
=> 10y - y = 4
=> 9y = 4
=> y = 4/9
Put the value of y in x - 3 = y
=> x - 3 = 4/9
=> x = 4/9 + 3
=> x = (4+27)/9
=> x = 31/9

Given:
- x+1=10y
- x-3=y
To Find:
- Values of x and y.
Solution:
- x-10y+1=0
- x-y-3=0
From 2nd equation,
- x=y+3
Using it in first equation,
- (y+3)-10y+1=0
Solving further,
- y+3-10y+1=0
- y-10y+3+1=0
- -9y+4=0
- -9y=-4
- y=4/9
Now finding x,
- x = y + 3
- x = 4/9 + 3
- x = (4 + 27)/9
- x = 31/9
