[tex]7x-5=0 => 7x=-5 => x=\frac{-5}{7}[/tex]
d)
[tex]3=2x+4 => 2x=3-4 => 2x=-1 => x=\frac{-1}{2}[/tex]
b)
[tex]2x-6=5x => 2x-5x=6 => -3x=6 => x=\frac{6}{-3} =-2[/tex]
e)
[tex]5x-8=2 => 5x=2+8 => 5x=10 => x=2[/tex]
c)
[tex]-8x+1=6x-10 => -8x-6x=-10-1 => -14x=-11 => x=\frac{14}{11}[/tex]
f)
[tex]11x-9=3x+3 => 11x-3x=3+9 => 8x=12 => x=\frac{12}{8} => x=\frac{3}{2}[/tex]
