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:

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((3)/(4)) - 36 = 0\\3x + (24)/(4)-36=0\\3x+6-36=0\\3x=36-6\\3x=30\\x=(30)/(3)\\x=10`

So, the value of x is 10

The solution is x = 10
