Observe each of them and identify if there is a mistake. If you think there is a mistake, try to explain what might have gone wrong. Then, correct it and give the value of the expression.

1. If $f = 4$, $g = 2$, then $2f – 2g = 2$. The correct expression is

$2 f - 2 g = 6$
$2 f - 2 g = 0$
$2 f - 2 g = 4$
$2 f - 2 g = 8$

2. If $t = 4$, $b = 1$, then $3t + b = 13$. The correct expression is

$3 t + b = 13$
$3 t + b = 12$
$3 t + b = 14$
$3 t + b = 8$
