Question

3x + 8y - 36 = 0

Answer 1

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:

$3x + 8y - 36 = 0\\3x + 8(\frac{3}{4}) - 36 = 0\\3x + \frac{24}{4}-36=0\\3x+6-36=0\\3x=36-6\\3x=30\\x=\frac{30}{3}\\x=10$

So, the value of x is 10

The solution is x = 10
