Answer :
[tex]7x-5=30\ \ |+5\ to\ both\ sides\\\\7x=30+5\\\\7x=35\ \ |:7\\\\x=\frac{35}{7}\\\\x=5\\\\Answer\ is\ x=5.[/tex]
7x - 5 = 30
* add 5 to both sides
7x = 30 + 5
7x = 35
* divided both sides by 7
(7/7)x = 35/7
x = 5
* add 5 to both sides
7x = 30 + 5
7x = 35
* divided both sides by 7
(7/7)x = 35/7
x = 5
