x2+11x+11 = 7x+9 x2+11x-7x+11-9 = 0 x2+4x+2 = 0 The above quadratic equation can be solved by using the quadratic equation formula and it will have two solutions.

The discriminant is 0.

11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2

7x + 8 = 11x + 3, solve for xsubtract 7x from both sides8 = 11x - 7x + 38 = 5x + 3subtract 3 from both sides5 = 5xdivide both sides by 51 = x.

2x = 11x + 4 Subtract 11x from both sides: -9x = 4 Divide both sides by -9: x = 4/(-9) = -0.444...

12x = 11x - 5, subtract both sides by 11x x = -5

(11 plus or minus the square root of 129) divided by 4x = 5.589454172900137x = -0.0894541729001368

Does it say solve for y?
