-11-8t=7t+7*2
-11-8t=7t+14 add 11 on both the sides
-11-8t+11=7t+14+11
-8t=7t+25
add 8t on both the sides
-8t+8t=7t+8t+25
15t+25=0
15t=-25
divide both the sides by 15
t=-25/15=-5/3 (;

ok wat u gotta do is to use distributive law
8*3-8*y=3y+2
24-8y=3y+2
add 8y on both sides
24-8y+8y=3y+8y+2
24=11y+2
then subtract 2 from both the sides
24-2=11y+2-2
22=11y
then divide both the sides by 11
22/11=11y/11
2=y
so y=2
