By arranging the equation

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

$= 20 t + 70 - 12 + t$ $=20t + 70 - 12 +t$

$= 21 t + 58$ $=21t + 58$

Your answer is $21 t + 58$ $21t+58$

$21 t + 58$ $21t+58$

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

$= (10 \times 2 t) + (10 \times 7) + (- 1 \times 12) + (- 1 \times - t)$ $=color(red)((10xx2t) + (10xx7))" "+" " color(blue)((-1xx12) + (-1xx-t))$

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

$= 21 t + 58$ $=21t+58$

How do you simplify 10(2t+7)−(12−t)10( 2t + 7) - ( 12- t )?
