Answer:
x = 10
Step-by-step 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)
