3x+12x = 15 15x = 15 x = 1
The answer to the problem of 12X plus 13 equals 9 is x equals -1/3.
9x + 2 = 12x + 14 -3x = 12 x = -4
x=5
x2+12x+11=0 (x+11)(x+1)=0 x=-11 or x=-1

10+12x=-14 -14-10=12x 12x=-24 x=-2

5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
3x+12x = 15 15x = 15 x = 1
The answer to the problem of 12X plus 13 equals 9 is x equals -1/3.
6x + 12x + 2x = 80 20x = 80 x = 4
9x + 2 = 12x + 14 -3x = 12 x = -4
12x - 8 = 10x + 42x = 12x = 6
-7+x=13x the -7=12x and x =-7/12
