Question 241684
To simplify this expression: {{{3(a-2b)-5(2a-b)}}}
We must first distribute the coefficients of the parentheses, then combine like terms.
{{{3(a-2b)-5(2a-b)}}}
{{{3a+(3*(-2b))+(-5*2a)+(-5*(-b))}}}
{{{3a-6b-10a+5b}}} ...same as... {{{3a-10a-6b+5b}}}
Simplified: {{{-7a-b}}}
.
Done!  :)
