There are no solutions. To prove this, use the distributive property, then solve for $t$ $t$ .

$0.2 (7 + 2 t) = 0.4 t + 14$ $0.2(7+2t)=0.4t+14$
$1.4 + 0.4 t = 0.4 t + 14$ $1.4+0.4t=0.4t+14$

Hold on a second...

$1.4 + 0.4 t - 0.4 t = 0.4 t - 0.4 t + 14$ $1.4+0.4t-0.4t=0.4t-0.4t+14$
$1.4 \neq 14$ $1.4!=14$

No solutions! This is something to keep in mind:
Just because there's an equation doesn't always mean that there's a solution.
