Answer:
Solve for b in the equation 3 (b + 6) = 27
Step-by-step explanation:
Sam and Brandon's age illustrates linear equations.
The method to solve Brandon's age is the method of substitution.
Let:
[tex]S \to[/tex] Sam's age
[tex]B\to[/tex] Brandon's age
From the question, we have:
[tex]S = 27[/tex]
[tex]S = 6 + 3B[/tex]
To solve for B, we simply substitute 27 for S.
So, we have:
[tex]27 = 6 + 3B[/tex]
Collect like terms
[tex]27 - 6 = 3B[/tex]
[tex]21 = 3B[/tex]
Divide both sides by 3
[tex]7 = B[/tex]
[tex]B = 7[/tex]
Hence, the method of substitution is used to solve for Brandon's age.
