Answer:
[tex]\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})=1-\frac{9}{7}n[/tex]
Step-by-step explanation:
Given : Expression [tex]\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})[/tex]
To find : Combine like terms to create an equivalent expression ?
Solution :
Step 1 - Write the expression,
[tex]\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})[/tex]
Step 2 - Apply distributive property, [tex]a(b+c)=ab+ac[/tex]
[tex]=\frac{1}{7}-3\times \frac{3}{7}n+3\times \frac{2}{7}[/tex]
[tex]=\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}[/tex]
Step 3 - Combine like terms,
[tex]=\frac{1}{7}+\frac{6}{7}-\frac{9}{7}n[/tex]
[tex]=\frac{1+6}{7}-\frac{9}{7}n[/tex]
[tex]=\frac{7}{7}-\frac{9}{7}n[/tex]
[tex]=1-\frac{9}{7}n[/tex]
Therefore, [tex]\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})=1-\frac{9}{7}n[/tex]
