1. 5-(6-x)=4(3-2x)
2. (x+1)(x+9)=(x+3)(x+5)
3.\(\frac{3\left(5x-2\right)}{4}\) -2=\(\frac{7x}{3}\)-5(x-7)
4. 3(x+1)(2x+5)=3(x+1)(7x-4)
5. (x-2)2-(3x+1)2+x(4x-1)=0
1. a/x(x-3)-x^2=6
b/(x-2)^2 +x(3-x)=5
c/(x-2)(x+1)=x^2=6
d/(x-2)(x+2)-x(x+4)=5
e/(x-3)(x^2+3x+9)-x^3+x=7
f/x^2+3x+2=0
h/(x-1)(x-5)+(3-x)(1+2)=7
l/(x+2)^2-(x-1)^2=0
