Bonsoir,
a.
[tex]2x-5 = 5x+1\\
2x-5x=1+5\\
-3x = 6\\\\
-x = \dfrac{6}{3}\\\\
-x = 2\\ \boxed{x = -2}\\\\\\[/tex]
b.
[tex]3-7x=3x+2\\
-7x-3x=2-3\\
-10x=-1\\
-x=\dfrac{-1}{10}\\\\ \boxed{x = \dfrac{1}{10}}\\\\\\[/tex]
c.
[tex]5x-6=-x+3\\
5x+x=3+6\\
6x=9\\
x=\dfrac{9}{6}\\\\ \boxed{x= \dfrac{3}{2}}\\\\\\[/tex]
d.
[tex]2x-\dfrac{1}{3} = 1\\\\
2x = 1 + \dfrac{1}{3}\\\\
2x = \dfrac{3}{3}+\dfrac{1}{3}\\\\
2x = \dfrac{4}{3}\\\\
x = \dfrac{\dfrac{4}{3}}{2}\\\\
x = \dfrac{4}{3} \times \dfrac{1}{2}\\\\
x = \dfrac{4}{6}\\\\ \boxed{x = \dfrac{2}{3}}[/tex]
