x/6 + 3 =9. Am I supposed to divide the six into the x and then add the 3? The answer I was getting was 3, and then I found out that it was wrong and I would like to know where I went wrong.
\n" ); document.write( "When you have an equation multiply thru by the least common multiple of the
\n" ); document.write( "denominators to cancel all the denominators
\n" ); document.write( "Your Problem:
\n" ); document.write( "Multiply thru by 6 to get:
\n" ); document.write( "x+18 = 54
\n" ); document.write( "x= 36
\n" ); document.write( "-----------------------------------------------------------------
\n" ); document.write( "An arithmitic student needs an average of 70 to recieve credit. She scored 82,64 and 98 on the first three exams. I am looking for a equality representing the score she must get on the last exam to recieve credit for the course.
\n" ); document.write( "Let \"x\" be the score she needs.
\n" ); document.write( "-Average is the sum of the scores divided by the number of scores:
\n" ); document.write( "EQUATION:
\n" ); document.write( "(82+64+98+x)/4 = 70\r
\n" ); document.write( "\n" ); document.write( "244+x = 280
\n" ); document.write( "x = 36 (She needs to get at least 36 on the 4th test)
\n" ); document.write( "===========\r
\n" ); document.write( "\n" ); document.write( "--------------------------------------------------------------------
\n" ); document.write( "Is 15 a solution to the equation 8-x=7?
\n" ); document.write( "Substitute and see if you get a true statement:
\n" ); document.write( "8-15 = 7
\n" ); document.write( "-7=7
\n" ); document.write( "15 is not a solution
\n" ); document.write( "--------------------------------------------------------------------
\n" ); document.write( "Solve for x, 3x-2y=6.
\n" ); document.write( "3x = 2y+6
\n" ); document.write( "x= (2/3)x + 3
