[latex] frac{1}{2}r - 2 = 3r + 5 \ frac{1}{2}r = 3r + 5 + 2 \ frac{1}{2}r = 3r + 7 \ frac{1}{2}r - 3r = 7 \ (frac{1}{2} - 3)r = 7 \ (frac{1}{2} - frac{6}{2} )r = 7 \ -frac{5}{2}r = 7 \ r = frac{7*2}{-5} \ r = -frac{14}{5} [/latex] Replace r by the result on both side of the 1st equation to make the result is the right one.
