I understand and can figure out that 1/3(s+6)=3 and that 's' is -3 (I think) but what I don't get is 2/3(x18)=-6. I DON'T GET IT!!! What's the answer and how do I get it? Please help!My teacher tried to help with a diffrent problem, 2/3x=12 with 'x'being 18 she wrote out the way to solve it but it still dosn't make any sense to me \n" ); document.write( "

Please help!My teacher tried to help with a diffrent problem, 2/3x=12 with 'x'being 18. \n" ); document.write( "----------------- \n" ); document.write( "Let's look at the three equations you mentioned: \n" ); document.write( "1st: (1/3)(x+6) = 3 \n" ); document.write( "Multiply both sides by 3 to get------- \n" ); document.write( "x+6 = 9 \n" ); document.write( "Subtract 6 from both sides to get----- \n" ); document.write( "x = 3 \n" ); document.write( "================================ \n" ); document.write( "2nd: (2/3)(x18)= -6 \n" ); document.write( "Multiply both sides by (3/2) to get--------- \n" ); document.write( "x18 = -9 \n" ); document.write( "Divide both sides by 18 to get------------ \n" ); document.write( "x = -1/2 \n" ); document.write( "------------------- \n" ); document.write( "(2/3)x = 12 \n" ); document.write( "Multiply both sides by (3/2) to get: \n" ); document.write( "x = 18 \n" ); document.write( "------------------ \n" ); document.write( "cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
