give me some time to figure out number 2 and 3
anonymous
  • anonymous
i keep on coming up with the wrong answer for all 3 of them and dont know how
anonymous
  • anonymous
5x-3=12x+11 First subtract 5x from both sides: -3 = 7x + 11 Subtract 11 from both sides: -14 = 7x Divide by 7 on both sides: x = -2
anonymous
  • anonymous
oh i was trying to add 5 to both sides
anonymous
  • anonymous
oh do you get the second one? or do you need explanation?
anonymous
  • anonymous
do i add -7 to 2(3p+6)
anonymous
  • anonymous
you multiply: -7(5p) + -7(3) and that gives you an equation as: -35p + -21-49 = 6p +6
anonymous
  • anonymous
so at the end your equation is -76 =9p and then you get the answer by dividing 9p to -76
anonymous
  • anonymous
that what i got but i get -8.4 it does not look right
anonymous
  • anonymous
the third answer is 22 + 11n and i don't know if you want me to simplify it or keep it like this
anonymous
  • anonymous
hmmm let me try the second answer again...
anonymous
  • anonymous
