Question 610679
(1)t=-4
(2)t=-3
(3)c=-4
(4)i=8             example:-2(2t+8)+5=5
                -2(8+2t)+5=5
                (8*-2+2t*-2)+5=5
 rewrite  (-16+5=-11
combine like terms -16+5=-11
    -11+-4t=5
solve -11t-4t=5
move all terms containing t to the left side,everything else to the right side
add-11+11t-4t=5+11
combine
-11+11=0
0t-4t=5+11
-4t=16
divide each side by -4
t=-4
