Explanation:
No 6
Given the equation:
[tex]6=n-4[/tex]To solve for n, add 4 to both sides of the equation:
[tex]\begin{gathered} 6+4=n-4+4 \\ 10=n \end{gathered}[/tex]The value of n is 10.
No 7
Given the equation:
[tex]r-2=5[/tex]To solve for r, add 2 to both sides of the equation:
[tex]\begin{gathered} r-2+2=5+2 \\ r=7 \end{gathered}[/tex]The value of r is 7.
