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!
9x + 8 = 6x + 20(- 8 from both sides)9x = 6x + 12(- 6x from both sides)3x = 12(divide both sides by 3)x = 4
no
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)
9x + 2 = 12x + 14 -3x = 12 x = -4
12x + 131 = 189 + 3x 12x - 3x + 131 - 189 = 0 9x - 58 = 0 9x = 58 x = 6,44444
Add 9x to each side: 12x + 11 = -25Subtract 11 from each side: 12x = -36Divide each side by 12: x = -3
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
-20 + 9x = -17-20 + 17 = -9x-3 = -9x |: (-9)0.333... = xx = 0.333...
-7 (negative 7) transpose the 9x then transpose the 6. divide both sides by 3x and your answer will be -7 =]
12x + 17 - (9x - 2)Eliminate parentheses:12x + 17 - 9x + 2Combine the 'x' terms:3x +17 + 2Combine the numerical terms:3x + 19
It is: 12x+9
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!
12x+14
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.
3x+27=12x-45 Bring x to one side and the numbers to the other 45+27=12x-3x 72=9x x=8 For any step you don't understand message me
