Question 252999
{{{3*abs(x)-5*abs(y)}}} Start with the given expression.



{{{3*abs(-7)-5*abs(-11)}}} Plug in {{{x=-7}}} and {{{y=-11}}}



{{{3*(7)-5*(11)}}} Take the absolute value of -7 to get 7. Take the absolute value of -11 to get 11.



{{{21-55}}} Multiply



{{{-34}}} Subtract



So {{{3*abs(x)-5*abs(y)=-34}}} when {{{x=-7}}} and {{{y=-11}}}
