12x = x + 3 11x = 3 x = 3/11
-2
Add 9x to each side: 12x + 11 = -25Subtract 11 from each side: 12x = -36Divide each side by 12: x = -3
(x - 1)(x - 11) x = 1,11
4x2 is 8+ 12x + 3 collect like terms, 8+3= 11, 12x+11 to solve for x, transpose the 11 to the other side of the = sign, 12x=-11, divide by 12, x=-11/12
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
x2+12x+11=0 (x+11)(x+1)=0 x=-11 or x=-1
12x = x + 3 11x = 3 x = 3/11

x=5/2*sqr(3)
Add 9x to each side: 12x + 11 = -25Subtract 11 from each side: 12x = -36Divide each side by 12: x = -3

Taken literally as...-0.2x + 12x + 11 = 0 (assuming nothing was lost during the question-asking process)...this equation as exactly one solution:-0.2x + 12x = -11x(-0.2 + 12) = -11x(11.8) = -11x = -11/11.8 = -110/118 = -55/59 = -0.9322
x2 + 12x - 11 = x2 + 12x + (12/2)2 - (12/2)2 - 11 = (x + 6)2 - 47
