Answer:
x = 10
Step-by-step explanation:
Coordinate pairs are given in the form (x,y)
So, since (x,3/4) is a solution, we can say
y = 3/4
Now we plug in y = 3/4 into the equation and solve for x:
[tex]3x + 8y - 36 = 0\\3x + 8(\frac{3}{4}) - 36 = 0\\3x + \frac{24}{4}-36=0\\3x+6-36=0\\3x=36-6\\3x=30\\x=\frac{30}{3}\\x=10[/tex]
So, the value of x is 10
The solution is x = 10
