need help with 2 questions first
It has been a long time since I did algebra and don't rememeber how to work the problems

1/5(x+1) + 2/5(x-1) = 3/10


2nd problem

0.1(2x-1) + 0.02(4x + 4) = 0.05x

  • algebra -

    the 2nd problems answer is 0.26 and the way i got that is by (2x-1)=1, 1x0.1=0.1x, then (4x+4)=8x, 8x0.02=0.16x, 0.16+0.1=0.26x
