The x- coordinate of the point which lies on the line represented by 5x - y - 7 = 0 and whose y - coordinate is 13, is

Solution:

Given, the equation is 5x - y - 7 = 0

We have to find the x-coordinate when the y-coordinate is 13.

Put y = 13 in the equation,

5x - 13 - 7 = 0

5x - 20 = 0

5x = 20

x = 20/5

x = 4

Therefore, the x-coordinate is 4.

Example: The x- coordinate of the point which lies on the line represented by x - y - 11 = 0 and whose y - coordinate is 1, is

Summary:

Given, the equation is x - y - 11 = 0

We have to find the x-coordinate when the y-coordinate is 1.

Put y = 1 in the equation,

x - 1 - 11 = 0

x - 12 = 0

x = 12

Therefore, the x-coordinate is 12.
