2x + 3y = 6
=> 2x = 6 -- 3y
=> x = 3 -- 3y/2

2x +3y=6 2x= -3y +6 then divide by 2 to get x=-1.5y +3. Now plug that back in for the value of x.
2(-1.5y +3) +3y =6
-3y +6 +3y =6
6=6

make x as the subject
2x = 6 - 3y
= 3(2 - y)
x = (3/2)(2 - y)

2x = 6 - 3y
x = (6-3y)/2
x = 3 - (3/2)y
you need a second equation to find a numerical value for x
# of variables = # of equations you need to solve all

2x = 6 - 3y
x = (1/2) (6 - 3y)

subtract 3y from both sides, then divide both sides by 2.
result: x=3-(3y/2)

2x+3y=6
2x=6-3y
x=(6-3y)/2
2x+3y=6
3y=6-2x
y=(6-2x)/3
