what is the answer

Question

What is

2x+3y=12

the missing value in the solution to the equation

Answer 1

Some solutions to the equation include the (x,y) pairs: (3,2) , (0,4) , (6,0)

Explanation:

2x + 3y = 12 is an equation with two unknowns, x and y. There are many possible answers.

For example

x = 3 and y = 2: 2(3) + 3(2) = 12

x = 0 and y = 4: 2(0) + 3(4) = 12

x = 6 and y = 0: 2(6) + 3(0) = 12

Answer 2

The equation is a straight downward sloping line

with slope = -2/3 and y intercept (0,4)

x intercept (6,0)

It's an inverse relation. As x increases, y decreases

As x decreases, y increases

As y increases, x decreases

As y decreases x increases

what's missing? If you knew x, you'd be able to solve for y

if you knew the y value, you could solve for x
