help rearanging a physics equation!?

Question

sry, im a total dumbass &can't figure this out.

delta d = (v1 +v2) / 2 x delta t.
im trying to solve for v1. help?

Answer 1

I'll rewrite the equation to avoid ambiguity
delta d = (v1 +v2) /( 2 x delta t)

multiply both sides of the equation by ( 2 x delta t) and we have
( 2 x delta t) x delta d = (v1 +v2)

finally solving for v1 we get
v1=( 2 x delta t) x delta d - v2
