12x + 131 = 189 + 3x 12x - 3x + 131 - 189 = 0 9x - 58 = 0 9x = 58 x = 6,44444

3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x

If this is algebra then; 3x plus 12x = 15x

9x + 2 = 12x + 14 -3x = 12 x = -4

3x + x + 8 = 204x + 8 = 204x = 12x = 3

no

The value of X in the equation 3x 2-12x plus 9 is 1.25.

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

x works out as 5/3

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

3x-8+5x+39+4x+51 = x(3+5+4) + -8 + 39 + 51 = 12x +82

3x=2x-12x=-12
