12x plus 131 equals 189 plus 3x?
12x + 131 = 189 + 3x 12x - 3x + 131 - 189 = 0 9x - 58 = 0 9x = 58 x = 6,44444
Combine like terms 3x plus 7 X2 plus 9x?
12x+14
What is the answer to 3x plus 11 equals -25-9x?
Add 9x to each side: 12x + 11 = -25Subtract 11 from each side: 12x = -36Divide each side by 12: x = -3
12x plus 6 equals 9x-15?
-7 (negative 7) transpose the 9x then transpose the 6. divide both sides by 3x and your answer will be -7 =]
9x plus 9 equals 135?
9x + 9 = 135 9x = 126 x = 14
12x plus 131 equals 189 plus 3x?
12x + 131 = 189 + 3x 12x - 3x + 131 - 189 = 0 9x - 58 = 0 9x = 58 x = 6,44444
Combine like terms 3x plus 7 X2 plus 9x?
12x+14

9x plus 9 equals 135?
9x + 9 = 135 9x = 126 x = 14
What is 9x-2 from 12x plus 17?
12x + 17 - (9x - 2)Eliminate parentheses:12x + 17 - 9x + 2Combine the 'x' terms:3x +17 + 2Combine the numerical terms:3x + 19
What is 7x - 4 equals 9x plus 10?
7x-4=9x+10-14=2xx=-7
What is 9x plus 3x plus 8 plus 1 in simplest form?
It is: 12x+9
What is the answer to 12x plus 6 equals 9x plus 27?
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!
Is this equation 9x plus 3y equals 12 and 12x plus 4y equals 18 parallel?
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.
2y-9x equals 14 solve for y?
2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2
What is 3x plus 27 equals 12x-45?
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
