The solution is (5, -2) Take the second equation and rewrite it as j = k + 7 Next plug this into the first equation in place of the j. SO...k + 7 + k = 3 2k + 7 = 3 subtract 7 from both sides 2k + 7 -7 = 3 - 7 2k = -4 divide both sides by 2 k = -2 Plug -2 back in to the equation j = k + 7 j = -2 + 7 j = 5
