You use inverse operations !!
If: v = u+at Then: -u = -v+at or u = v-at (by dividing all terms by -1) a = (v-u)/t t = (v-u)/a
Addition is commutative.
T = 4x + 8 Subtract 8 from both sides: T - 8 = 4x Divide both sides by 4: T/4 - 2 = x or x = T/4 - 2
2t
t=-10
v
467
Yes and t = 1 in both equations
It is the same as: 2s = t
-90
t
(7 + 8)/3 = t Therefore, t = 5.
