Full solution

Q. Solve for rr.105r=6r1 r=\begin{array}{l} -10-5r=-6r-1 \ r=\dots \end{array}
  1. Given System of Equations: We are given the system of equations:\newline105r=6r1-10 - 5r = -6r - 1\newlineLet's isolate the variable rr on one side of the equation by adding 6r6r to both sides.\newline105r+6r=6r1+6r-10 - 5r + 6r = -6r - 1 + 6r\newlineThis simplifies to:\newline10+r=1-10 + r = -1
  2. Isolate Variable rr: Now, let's isolate rr completely by adding 1010 to both sides of the equation.\newline10+r+10=1+10-10 + r + 10 = -1 + 10\newlineThis simplifies to:\newliner=9r = 9
