we need to get y alone so subtract 2x from both sides of the equation
2x+4y=12
-2x -2x
-----------------------
4y=-2x+12 now divide both sides by 4
y = -2x/4 +12/4
y = -1/2 x +3
Proportional relationship is when the two fractions are equal and non-proportional relationships are when the fractions are unequal.

Answer:
x = -3
Step-by-step explanation:
-4x + 2(5x - 6) = -3x - 39
-<u>4x</u> + <u>10x</u> - 12 = -3x - 39
-4x + 10x = 6x
6x - 12 = -3x - 39
<u>+3x</u><u> _ </u><u>+3x </u>
9x - 12 = -39
<u> </u><u>+ 12</u><u> </u><u>+12</u>
<u></u>

x = -3
-30 = -30
