I assume you mean -9(e+4)=r+14, r+8e+3=46. The latter can be rewritten: r=43-8e which can then be substituted into the other equation: -9(e+4)=43-8e+14=57-8e. -9e-36=57-8e, -e=93 so e=-93. So r=43+8*93=787.
CHECK
-9(-93+4)=787+14=801, -9*-89=801; 787-8*93+3=46. Both equations are true for e=-93 and r=787.
