12x + 6=9x + 27

12x-9x + 6=9x - 9x + 27 subtract 9x from both sides.

3x + 6 = 27 simplify

3x + 6 - 6=27 - 6 subtract 6 from both sides.

3x=21 simplify

3x/3=21/3 divide both sides by 3

x=7 simplify

12(7) + 6=>84+6=>90

9(7) + 27=>63+27=>90

It checks out!

x = 5

9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3

Presumably this is a quadratic equation question in the form of: 9x2-12x+4 = 0 When factored: (3x-2)(3x-2) = 0 Solution: x = 2/3 and also x = 2/3 (they both have equal roots)

no

Add 9x to each side: 12x + 11 = -25Subtract 11 from each side: 12x = -36Divide each side by 12: x = -3

-7 (negative 7) transpose the 9x then transpose the 6. divide both sides by 3x and your answer will be -7 =]

It is: 12x+9

Yes the equation is parallel and this is why.... when you put the formula 9x+3y=12 in a slope intercept form you'll get 9x+3y=12 9x+3y-12=0 3y= -9x+12 divide by 3 y=-3x+4 12x+4y=18 12x+4y-18=0 4y= -12x+18 divide by 4 y= -3x + 9/2 In order for two equations to be parallel the slope must be equal to each other remember the slop is the m in y=mx+b. Since both equations have -3 as it's slope that makes them parallel lines.
