Algebra.Com's Answer #192750 by butterfliiizzz(18)![]() ![]() You can put this solution on YOUR website! For this problem, it is telling you the value of y. So simply plug that in where the y is and then solve for x.\r \n" ); document.write( "\n" ); document.write( "2x - 6 = 5x + 15 So what I would do is subtract 5x from each side to get: \n" ); document.write( "-3x - 6 = 15 Now we can add six to both sides, to get rid of the negative 6. \n" ); document.write( "-3x = 21 Now, to get x by itself, we need to divide each side by -3. \r \n" ); document.write( "\n" ); document.write( "-3/-3 =1 We want 1x (or simply, x) on the left. On the right, 21/-3 = -7\r \n" ); document.write( "\n" ); document.write( "So x = -7 \n" ); document.write( " |
