-7(n - 2) + 2n = -5(n + 6)
skad [1K]

Given the expression below

-7(n-2)+2n=-5(n+6)

To find n

Open the brackets

\begin{gathered} -7(n-2)+2n=-5(n+6) \\ -7n+14+2n=-5n-30 \\ -7n+2n+14=-5n-30 \\ -5n+14=-5n-30 \end{gathered}

Collect like terms

\begin{gathered} -5n+14=-5n-30 \\ -5n-(-5n)=-30-14 \\ 0\ne-44 \end{gathered}

Since, the sides are not equal,

Hence, there is no solution

Keith = x
Troy = x-3
Joe = 2(x-3)
