What is the value of x? 3x-14+2x+9=90\r \n" ); document.write( "\n" ); document.write( "This goes back to Algebra problem. First, arrange the equation from \n" ); document.write( "3x-14+2x+9=90 to... \n" ); document.write( "3x+2x-14+9=90. \n" ); document.write( "Combine the like terms. \n" ); document.write( "3x+2x=5x. \n" ); document.write( "-14+9=-5. \n" ); document.write( "So it ends up like this: 5x-5=90. Add 5 on each side, so it would be come \n" ); document.write( "5x=95. Remember that u always do the opposite of what it is doing: as it is \n" ); document.write( "subtraction, u make it addition. If you want to ask why, don't ask me :D. \n" ); document.write( "5x=95. Now DIVIDE 5 on each side. In the end, you will end up with x=19. \n" ); document.write( "So, x=19. \n" ); document.write( "Now... to check: 3(19)-14+2(19)+9=90. Multiplication first. 19x3=57. 19x2=38. \n" ); document.write( "So it ends up with: 57-14+38+9=90. Add em' all up. 57-14=43+38=81+9=90. \n" ); document.write( "90=90. So answer is x=19. Still confused? Well... you shouldn't be. \n" ); document.write( "--- \n" ); document.write( "I like math, period. \n" ); document.write( " \n" ); document.write( " |
