By arranging the equation

$10(2t+7) - (12-t)$

$=20t + 70 - 12 +t$

$=21t + 58$

Your answer is $21t+58$

$21t+58$

$=color(red)(10(2t+7)) + color(blue)(−1(12−t))$

$=color(red)((10xx2t) + (10xx7))" "+" " color(blue)((-1xx12) + (-1xx-t))$

$=color(red)(20t + 70)" "+" "color(blue)(-12 + t)$

$=21t+58$
