Algebra.Com's Answer #269720 by robertb(5830)![]() ![]() You can put this solution on YOUR website! Right. After substituting y into the bottom equation, you should get 5(5x-8) = 2x + 6. From here you can solve for x. After solving for x, get back to the top eqaution y = 5x - 8, and then solve for y. =) \n" ); document.write( " |
