Algebra problem i can't figure it out?
January 7th, 2009 by cfz
3-2x-12=7x-4
-9-2x=7x-4
-5=9x
-5/9=x
1st distribute the -2
3-2x-12=7x-4
then combine like terms
3-12=-9
-9-2x=7x-4
then add 2x to 7x because they are like terms
-9=9x-4
then add 4 to -9
-5=9x
then divide by 9
x=-5/9
hope im right
=)
combine like terms and you get -2x+15=7x-4
add 2x to both sides and subtract 15 from both sides and you get:
9x-19=0, then add 19 to both sides
9x=19
divide each side by 9 and you get x=0.47368421052631578947368421052632
3-12=9x-4
-9=9x-4
-5=9x
x=-5/9
