so -6x +22= 7 -22 -22 --------------- ? There you gp

then divide -6x for both side of the equation
anonymous

thx for writing it for me

Your welcome :)
anonymous
  • anonymous
no i mean divide -6 for both side of the equation
anonymous
  • anonymous
huh?
anonymous

so we want x to be alone after all we are solving the value of x

19 - 3(2x - 1)=7 19 - 6x + 3 = 7 - 6x + 22 = 7 -6x = 7 - 22 -6x = -15 x = -15/(-6) x = 5/2 x = 2.5 I would personally go with x = 5/2, but x = 2.5 works just as well
anonymous
  • anonymous
sorry i was wrong
anonymous
  • anonymous
sorry, my mestake, but this is the answer x = 2.5
