Question 210635
I'll do the first one to get you started.


# 1


{{{a(3tx-2b) = c(dx-2) }}} Start with the given equation.



{{{3atx-2ab=cdx-2c }}} Distribute



{{{3atx=cdx-2c+2ab }}} Add 2ab to both sides.



{{{3atx-cdx=-2c+2ab }}} Subtract cdx from both sides.



{{{x(3at-cd)=-2c+2ab }}} Factor out the GCF 'x'



{{{x=(-2c+2ab)/(3at-cd) }}} Divide both sides by {{{3at-cd}}}.
