Answer:

[tex]b=6[/tex]

Step-by-step explanation:

[tex]7b-15=5b-3[/tex]

Subtract [tex]5b[/tex] from both sides: [tex]2b-15=-3[/tex]

Add [tex]15[/tex] to both sides: [tex]2b=12[/tex]

Divide both sides by [tex]2[/tex]: [tex]b=6[/tex]
7b - 15 = 5b - 3
-5b -5b
—————————
2b - 15 = -3
+ 15 +15
______________
