Question 973192

{{{((2x-1)/3) + ((1-3x)/7) = 7-2x}}}

you multiplied both sides by {{{3}}}:

{{{2x-1 + ((3-9x)/7) = 21-6x}}}..... that is correct

Next you multiply through by {{{7}}}:

{{{14x-7 + 3-9x = 147-42x}}}..... that is correct

{{{5x-4 = 147-42x}}}

{{{5x+42x = 147+4}}}

{{{47x = 151}}}

{{{x = 151/47}}}=> this is {{{exact}}} {{{solution}}}

or approximately {{{x = 3.212765957446809}}}=>{{{x = 3.21}}}
