Question

3x + 8y - 36=0

The point (x, 3/4) is a solution to the equation shown. What is the value of x?

Answer 1

x = 10

Explanation:

3x + 8y - 36 = 0 ( given )

3x + 8y = 36 ( change sides of 36 )

3x + 8 ( 3 / 4) = 36 ( implementing the value of y which is given )

3x - 2 * 3 = 36 ( 8 * 3 / 4 = 2 * 3)

3x - 6 = 36

3x = 36 -6

3x = 30

x = 30 / 3

x = 10

therefore the coordinates will be (10,3/4)
