Question 31484
All you need to do is rearrange each equation such that the variables are all on one side and the integers are on the other.  Your ultimate goal is to isolate the variable to find its value (i.e. x = #).

1. {{{4x + 5 -3(2x - 5) = 9 - (8x - 1) + x }}}


{{{4x + 5 - 6x + 15 = 9 - 8x + 1 + x }}}  
(simplify equation by removing parentheses, performing multiplication as necessary.)


{{{20 - 2x = 10 - 7x }}}  
(simplify each side by combining like terms.)


{{{7x - 2x = 10 - 20}}}  
(put all terms with variables on one side and all integers on the other.)


{{{5x = -10}}}  


{{{x = -2}}}  


2. {{{1 - (t - 1)= 2t}}}


{{{1 - t + 1 = 2t}}}


{{{2 - t = 2t}}}


{{{2 = 3t}}}


{{{2/3 = t}}}


3. {{{3x + 2 (x + 2) = 13 - (2x - 5)}}}


{{{3x + 2x + 4 = 13 - 2x + 5}}}


{{{5x + 4 = 18 - 2x}}}


{{{7x  = 14}}}


{{{x  = 2}}}
