Are you doing your math homework on a Sunday night, gcd?
Our school district has the entire week off for Thanksgiving. No math for our kiddos this week!

2v+18=4(v+7)...ok
2v+18=4v+28 so fare so good
-18 18
2v=4v+10
-4v -4v
-2v=+10
---- ----
-2 -2
V=-5
there
Check
2x-5+18=4x-5+28
-10+18=-20+28
8=8
Correct V=-5

The answer comes out the same somehow but The original equation was
2v+18=16-4(v+7)
2v+18=16-4v-28
-16 -16
2v+2=-4v-28
-2 -2
2v=-4v-30
4v 4v
6v=-30
v=-30/6
v=-5
