Answer 1

Step-by-step explanation:

solution:--2{-1(1-4)+2(4-2)+3(2-1)}+3{5(-3+5)-9(-5-2)-3(2+3)}

=-2{-1*(-3)+2*(2)+3*(1)}+3{5*(2)-9*(-7)-3*(5)}

=-2{3+4+3}+3{10+63-15}

=-2*{10}+3*{73-15}

=-20+3*{58}

Answer 2

Step-by-step explanation:

$-2{ - 1( - 3) + 2(2) + 3(1)} + 3{5(2) - 9( - 7) - 3(5)} = 154$

$- 2(3 + 4 + 3) + 3(10 + 63 - 15) = 154$

$- 2(10) + 3(73 - 15) = 154$

$- 20 + 174 = 154$

$154 = 154 \\ verified \: \\ plz \: do \: follow \: n \: mrk \: as \: brainliest$
