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
