Answer:
Solution:
[tex]b = \frac{22}{5?} [/tex]
Step-by-step explanation:
Rearrange terms:
[tex] - 3b + 7 = - 15 + 2b [/tex]
[tex] - 3b + 7 = 2b - 15[/tex]
subtract 7 from both sides of the equation:
[tex] - 3b + 7 = 2b - 15[/tex]
simplify:
subtract the numbers
⬇️
⬇️
[tex] - 3b = 2b - 22[/tex]
subtract ⬇️ from both sides of the equation
[tex]2b[/tex]
[tex] - 3b = 2b - 22[/tex]
[tex] - 3b - 2b = 2b - 22 - 2b[/tex]
simplify:
⬇️combine like terms
⬇️combine like terms
[tex] - 5b = - 22[/tex]
divide both sides of the equation by the same term:
[tex] - 5b = - 22[/tex]
[tex] \frac{ - 5b}{ - 5?} = \frac{ - 22}{ - 5?} [/tex]
simplify:
⬇️cancel terms that are in both the numerator and the denominator
⬇️divide the numbers
[tex]b = \frac{22}{?5} [/tex]
