3x + 2y = 12
3x = 12 - 2y
x = (12 - 2y)/3
x = 4 - 2y/3
or
3x + 2y = 12
2y = 12 - 3x
y = (12 - 3x)/2
y = 6 - 3x/2

3x+2y=12?
3 times 2=6
2 times3=6
6+6=12
3 times 2+2 times 3=12

3x+2y=12 is a linear line with a slope (m) of -3/2 , a x-intercept of 4, and a y-intercept of 6.
Can be rewritten as y = -3/2 x + 6

x = 2, y = 3. Therefore, 3 x 2 = 6 and 2 x 3 = 6, which means 6 + 6 = 12.

Subtract 3x from both sides:
2y=-3x+12
Divide 2 from both sides:
y=-3/2x+6
Just plug in numbers for x to get the y-values and then make a graph out of the equation!

It's a linear equation in x and y. One could manipulate it to find that it is equivalent to y = (-3/2)x + 6, the equation of a line with slope -3/2 and y-intercept of 6. To find its x-intercept, we let y = 0, and find that x = 4.
You realize, of course, that x and y can be any real number, since a line contains an infinite number of points.
